Overview

Woo Ik-Han (Kor. 우익한) is an ordinary human and one of the supporting characters of the series. He is a student at Ye Ran High School and Shinwoo's best friend. He is also a close friend of Frankenstein's household, where he usually hangs out with the rest of his friends. He is very knowledgeable when it comes to technology and hacking.

His name in the anime is Manabu Kase (加瀬 学, Kase Manabu).

Appearance[]

Ik-Han is a pale, brown-haired boy who is 157 cm tall. His hair seems to change colour occasionally throughout the series, as it is seen being purple-blue in the second arc, though this seems to reflect the changes in art style more than a change in colour. He also wears spectacles. Though short, he is noted by some girls to be quite cute.

He is seen in different clothes but is most often wearing the Ye Ran uniform.

Personality[]

A running gag throughout the manhwa is Ik-Han's worry about his relatively short height. Initially, when Regis and Seira joined his class at school, Ik-Han showed extreme interest in the new students which others supposed was Ik-Han developing a crush on Seira. However, it is later revealed that Ik-Han was rather enraptured by Regis for he stated that he always wanted a fellow 'short' friend. Throughout his adventures, Ik-Han is seen giving Regis food and candy that are long and thin (such as pocky) stating that he and Regis must eat them to grow taller (a pun on the stature of the food).

Ik-Han has a lot of pride when it comes to dealing with technology and he has the tendency to show off or become happy when people praise him. He looks up to Tao as his 'hyung' because they are both hacking experts. Ik-Han values his friends and is not afraid to stand up to others to save them. He can be rambunctious and mischievous, though he often reprimands Shinwoo for his behaviour.

Background[]

Ik-Han is a regular human. He is childhood friends with Shinwoo and Yuna, and also very close to Suyi[1], Regis, Seira and Raizel. He spends most of his day on his laptop and is stated to live with his uncle who is in the police force.

Plot Overview[]

Ik-Han is introduced when Raizel joins Pedro's class[2]. He sits next to Raizel and is often shown tapping away on his computer as Raizel watches him interested in what he is doing[3]. At dinner, Ik-Han tells Shinwoo he's forgotten his wallet, and so Shinwoo treats both him and Raizel to ramen[4].
Ik-Han befriends Raizel with Shinwoo and Yuna. They go through introducing him to different things, and later encounter the infected[5]. Afterwards they guide Raizel back home as he is lost. The next day they learn that the murderer suspected for a massacre is the infected they ran into and decide to stick together. Still, they all are easygoing and take Raizel to the computer cafe to play games. They also come across M-21 and M-24 later[6].
Ik-Han lets Shinwoo stay over when he is threatened by M-21 and M-24 leaving his bag in front of his apartment. The two also rush to Yuna's rescue when she is kidnapped by them, though Ik-Han calls Frankenstein first[7]. Frankenstein and Raizel arrive while Shinwoo fights the infected and rescue the children. Some other day, the children visit Raizel at Frankenstein's house, but get arrested by the police for climbing over the fence since Raizel doesn't know how to open the door.
Later on, the children are once again kidnapped, but this time by Jake and Mari[8]. Shinwoo is forced to fight the infected and then Jake to protect Ik-Han and Yuna, however M-21 and M-24 step in to help them flee after calling Raizel. The children witness M-24's death after protecting them, as well as Raizel's powers. Despite this, their memories of the incident are erased afterwards[9].

Ik-Han, Shinwoo, and Yuna bring Suyi along when they visit Raizel at Frankenstein's home. When Seira and Regis first join their class, Ik-Han takes interest in Regis because of his similarly short stature[10]. He and the other children end up befriending the two.
When DA-5 come to Seoul, Ik-Han ends up protecting the police data from Tao as he attempts to hack into it[11]. Tao, not expecting any opposition at all, is impressed with Ik-Han skill and compliments him. Shinwoo mistakes the entire thing as Ik-Han flirting with a girl online. Later, Tao meets Ik-Han in person.
Once again, the children are captured, this time by Hammer to save Shark who is losing to Regis. Ik-Han recognises Tao and is confused, and they all recognise M-21. When pushed, M-21 protects them along with Regis until Raizel arrives to save them. When Kranz is about to absorb Tao, Ik-Han begs Tao not to follow Kranz's order as he had attempted to help him and the other children. He then begs Raizel to save him along with the other children, at which Raizel says that it is unnecessary for them to beg him because they are his friends. Once rescued they are told everything but still have their memories of the event erased.
When Ik-Han and the other children see Takeo and Tao join the security team, they express joy[12].

Ik-Han and Shinwoo drag Raizel and Regis with them to a blind date[13].

Suyi arranges for their friend group to come to one of her photo shoots. Despite the set director's initial cold attitude, he warmed up after Shinwoo and Ik-Han helped out with some problems[14]. Again the children visit Frankenstein's home and more shenanigans ensue.
Yonsu and Sangeen are sent out to test Ik-Han and Shinwoo as possible recruits for the KSA[15], Ik-Han because of his intelligence and hacking skills. The two join as teachers at Ye Ran to do so.

Yuri, Mark, and Kalvin kidnap the children, using them as blackmail to gain Frankenstein's data[16]. They are unconscious throughout the event and are saved by the RK and Rael.

The children are shown at Frankenstein's home[17] and school[18].

Raskreia comes to school and the children get to know her[19]. They suspect that Raizel has feelings for her. Later Ik-Han and Shinwoo invite Rael, Raizel, and Regis for a meeting for the 'lonely'[20].
Some other day, Rael and Regis escort the children home, though Rael leaves midway due to detecting strange activity[21]. The security trio and Regis are hurt in the ensuing fight, which causes only Seira and Raizel to return to school after the weekend. This worried the children though they end up accepting Tao's excuse for why everyone else was missing[22].
The children are shown walking into school with Raizel, Regis, and Seira[23].

Noticing that Raizel has been looking weaker, the children decide to make something nice for him to eat. Shinwoo and Ik-Han rush off after class to buy the ingredients, and after doing so go to play some games. They beat some people repeatedly, who end up being in the same computer cafe. As such when the two get up to leave they try to beat them up. This fails as Shinwoo beats them, however, the bullies vow to get revenge[24].
A few days after the incident, Ik-Han is at Frankenstein's house with his friends. Suyi interrogates him and Shinwoo about it due to the rumours going around. She is upset at them for causing trouble, as well as lying to everyone else about why they were late[25].
In a flashback, Raizel recalls Shinwoo and Ik-Han telling him how lucky he is to be part of a large family, since their families are smaller and their homes feel empty compared to Raizel's[26]. After the battles in the werewolf lands, everyone returns and the children are happy to see them[27]. Raskreia once again visits school and the children set up a 'date' between her and Raizel, however, it only leads to them learning about how Raizel treasures his time with them so they continue as normal afterwards.
After she leaves they meet Muzaka. As they think that he's Raizel's friend, they take him around on their routine after school[28].
Upon the craters caused in Seoul due to Crombel's attacks, the children zoom into the photo taken of the scene and suspect that Raizel is involved[29]. They head to Frankenstein's home and ask Raizel about it[30], so he tells them the truth. They also find out about Muzaka and Raskreia. Due to further attacks Tao takes them to a safer place. In the epilogue the children go to school on a normal day, though they have completely forgotten about everything. However, when they see Raizel, they remember it all and are overjoyed[31].

Woo Ik-Han does not feature in the Beginning Of Destruction OVA.

Like in the manhwa, Ik-Han becomes Raizel's friend. He and the other children drag Raizel away when they first meet the Infected, under a bridge instead of in an alleyway. The kidnapping by M-21 and M-24 does not occur as Jake and Mari arrive sooner. As in the manhwa they are kidnapped by them.

Episode 1
Ik-Han (Manabu) and Shinwoo (Tashiro) walk to school after Shinwooo's hospital stay due to the events that occurred in the Awakening OVA. When Ik-Han says that Shinwoo should have stayed longer since he can't even write with his right arm in a cast, Shinwoo slaps his back and says Ik-Han can take his notes for him. At the school gates, they see and greet M-21 who's the new security guard. Ik-Han calls Shinwoo a klutz when Shinwoo answers M-21 about his inquiry on his cast, and is immediately put into a headlock as Shinwoo says he got hit by the car to save him.
In class, Ik-Han is the one keeping Shinwoo in a headlock so that their male classmates can write joking insults on his cast. They greet Raizel when he enters the classroom and Ik-Han calls the doodle he makes on the cast cute, saying that it matches Shinwoo's scary face. During class, Ik-Han tells Shinwoo that he can't use his phone when the latter takes pictures of the notes on the board. While they're eating in the cafeteria, Ik-Han asks Raizel why he's not eating to which he gets the answer 'I'm waiting for it to multiply'. At the end of the school day, Ik-Han packs Shinwoo's bag for him, and answers that he has indeed gotten the new released game. He then invites Raizel over to his house as well. Raizel doesn't end up joining them because they realise he doesn't have a phone to inform Frankenstein that he has made plans.
The next morning, they once again greet M-21 as they come to school and are surprised to see that Raizel has a phone. Ik-Han comments that it's the latest model and teaches him how to use the phone while getting his phone number and email address. The three are eating lunch, with Ik-Han eating omurice, when there is a commotion at the gates. Ik-Han and Shinwoo go to see what's happening and when Shinwoo is accused of flirting with the instigator's girlfriend, Ik-Han asks him if he did something with a scandalised expression. He's shocked to learn that all Shinwoo did was catch the woman when she fell, and backs away with the janitor when it becomes obvious there will be a fight.
When Shinwoo falls through a hedge after being punched, Ik-Han looks worried and calls out his name. He calls his name again later in the fight, though this time Shinwoo is pushed back into him and they both fall to the ground. They thank M-21 after he intervenes and saves them.
Episode 2
Ik-Han is talking to some classmates when Shinwoo arrives; he berates him, saying he should wake up sooner. When Regis and Seira introduce themselves, he's too distracted staring at them to answer Shinwoo. During their break, Ik-Han, who eats curry, pays for their meals. Since he's still staring with an excited expression, Shinwoo thinks that he has a crush on Seira.
After school at Frankenstein's home, Shinwoo attempts to set Ik-Han up with Seira. Upon Frankenstein and M-21's entrance, Ik-Han greets them and starts to clean up after Shinwoo lets him go from his headlock, and scolds him when he orders Frankenstein around. When he learns that M-21 is also staying there, he's impressed by Frankenstein's generosity.
At the end of the next school day, Ik-Han questions Regis' immediate disappearance after class and worries over whether he'll be able to find his way home while they're walking back. He's annoyed and confused when he bumps into Shinwoo's back, unaware of his attempts to set him up with Seira. Before any clarifications can occur, the group of men from the previous episode appear intending to harass Shinwoo. When the leader approaches Seira, Ik-Han stands in the way and is grabbed by him but Shinwoo intervenes.
The gang takes all of them to a construction site where Shinwoo signals Ik-Han to get Raizel and Seira to stand back, which he does. During the fight, Ik-Han remains worried and comments that there are too many guys for Shinwoo to fight. He also warns him to look out when the leader takes out a gun. After the fight, he asks whether Shinwoo is okay several times and tries to carry his bag for him.
Episode 3
At school, Ik-Han scolds Shinwoo for always getting into fights, mentioning that if M-21 hadn't been there, he'd have died in the previous episode. Shinwoo is still under the impression that he has a crush on Seira but realises he was mistaken when Ik-Han talks eagerly to Regis when he enters the classroom with Seira. Ik-Han offers to share his textbooks with him, puts their desks together, and asks about Regis' height. He's even more impressed by Regis aside from feeling kinship about being short when he says that being short isn't a big deal.
After school, Ik-Han and Shinwoo are at Ik-Han's house. Since Ik-Han is doing security checks on the police database for his uncle, Shinwoo cooks for both of them. Tao attempts to hack the database during the checks which excites Ik-Han. He focuses on preventing the hacker from gaining access but as things escalate, Shinwoo trips over his laptop's power cord causing it to shut off. Worried, Ik-Han switches it back on and realises that the hacker stopped when he lost power instead of continuing. He glares at Shinwoo when asked why the laptop needs constant power despite having a battery and gets up to call his uncle about the hacking attempt.
During the short while Ik-Han is gone, Shinwoo chats with Tao and comes to the conclusion that Ik-Han is gay and vows to protect him from any homophobes. Ik-Han scolds him for using his laptop when he returns.
Rest of summary coming soon.

Powers & Abilities[]

Ik-Han's hacking and computing skills are extremely proficient. He is also the best when it comes to video games, as it is mentioned by Shinwoo that Ik-Han defeats him every time. Ik-Han is shown to be quite brainy rather than brawny, taking school much more seriously than Shinwoo.

Hacking[]

Ik-Han's computer skills are very proficient. He was able to match Tao's speed and stop him when Tao tried to hack into Ik-Han's uncle's police databases[32], though later it is shown that Tao easily outstrips him. Even the KSA selected him as a candidate for trainee because of his top-notch hacking skills (as revealed by Na Yonsu)[33].

Gaming Expertise[]

Ik-Han is also into gaming, like Shinwoo. It is one of their favourite ways to kill time. They often bring games to play with Raizel in the Principal's house. Ik-Han has a high level of expertise in games, however, he, along with his friends, lose against Raskreia on her very first try.
