Have to stop at chapter 66, it goes more beyond that but things just went off from the premise/title before the guerilla training arc.
Mc, jinsung, has this dilemma and sort of a problem. To start of the world building is amazing, there are no hunter or monsters but a simple alternate world where magic, skills, abilities and techniques are real and they're called Ideya. Ideya is the manifestation of this thins and they are divided in ranks. s/ss or above is highest until f the lowest. And there is also combat ability that is like a physical capability of the person, this also gets divided in rank, same as ideya. Aside this, there is a hierarchichal prejudice when it comes to rankings. your social value is proportionate to your ranking. if your ideya and combat ability is low, society thinks lowly of you. But do not fret, ideya and combat ability can increase with training.
Back to the story, mc has this problem and he has to hide his true ideya rank. In turn, he gets treated poorly by his colleagues. Although mc sometimes let himself loose, it's for him to escape bullying.
mc meets with ahnseyoung, a person just like mc with "weak" ideya but simply improved himself to get the title of ace in their school. during a match mc and his team went up against ahnseyoung. ahnseyoung comes out rude at mc but somehow mc showed a bit of his power. ahnseyoung becomes interested in mc, ahnseyoung and mc are both male btw. ahnseyoung sees mc as a prospect training buddy.
mc then meets seyun, the possessor of the goblin ideya, something like a renowned hereditary ability. seyun shows interest towards mc and sees him as husband candidate. seyun is female.
bank robbery arc, mc, seyun along with there classmate is sent to off school activity and that is guard duty to a bank. things are going smoothly until robbers/terrorist arrives. mc hides. seyun faces the terrorist. seyun gets overwhelmed from the terrorist lead. witg things going bad, mc manages to lure the terrorist to a 1v1 match. mc overwhelms the terrorist. unfortunately, the terrorist lead manages to escape thanks to one of mc's school bully. mc in his true ideya form, ran after the school bully but he was stopped by seyun.
let's talk about mc's ideya. mc's ideya is ranked f, a normal dagger. nothing much, just a dagger. but that isn't just mc's ideya. mc has a second ideya, rank s, murder. mc changes personality to a psychotic bloodlust filled murderer and his target will always be the closest human. thanks yo the murder ideya, mc's combat ability reaches s rank as well. unfortunately, mc does not have control of himself and will indiscriminately go to a murderspree, whether foe or ally. will only stop if mc's bloodlust gets satiated or gets knocked out.
mc wakes up, and was fearful for seyun, although mc is in frenzy, mc remembers everything that happened. fortunately seyun is fine. mc vows to get strong. mc goes to ahnseyoung for training.
guerilla arc, mc forms a bond with the team given to him. the team is named, zombie horde, as they are lowest of the low ranks but through their will, they keep pushing through despite how rough up they become through training. also in this arc, the clear discrimination is shown, from the instructors and even the principal of the school. in the final showdown, the trench battle, the zombie horde showcased their growth from their low rank and their loyalty to mc. mc won the battle despite being called fake and even the reporter that covered the event was even said to have been bribe to make mc look good despite not being true.
next is the terrorist arc, after the guerilla training, a new character appears, the husband candidate picked by seyun's family for her, petch. seyun does not like petch. they all misunderstood mc. they thought it was mc who is seduced seyun. in fact, it was seyun who was taking the initiative towards mc. and mc is going along. petch as well seyun's family belittle's mc, this is thanks to the fact that mc is still f rank and not much info is still revealed about him to many. mc and petch had a first spar. petch rudely belittle mc. mc reveals a bit of his power. petch is taken aback to what he witness but still, he is not satisfied with mc being seyun's choice of husband to be.
meanwhile, certain terrorist group is brewing their act. first there was a giant bear that is believe to be an ideya, that wrecked havoc. south korea's greatest, li xinwin.. something managed to faced off against it.
back to the school, mc had another confrontation with petch. mc goes almost all out. mc understood why petch is the chosen candidate for seyun. petch has a plunderer ideya, seyun's family does not like the armor ideya of seyun and that's why they plan on having petch take the hereditary goblin ideya of seyun.
a bit of self though regarding seyun's ideya. her ideya is the goblin spirit swordsmanship. but instead of going all offensive, seyun does not like doing harm so instead of this, seyun focuses on the defensive capability of her ideya. or something like that.
back to the round 2 of mc vs petch. mc goes almost all out, mc wins. after the match, petch reveals to mc that seyun's family wants to speak with mc. mc has no say to this. mc went and spoke with the family head of seyun. they still think mc is not a good match to mc. mc does not focus on denying it, instead, mc tells them off and that seyun should be able to choose her path.
this is again in my understanding, seyun's family wants her to become an all offensive goblin ideya user, this is despite the fact that seyun's swordsmanship and combat ability subpar. add to this that seyun, is more like a pacifist or something? she does not like hurting others, although she seemed that way since that is how her upbringing is.
seyun appears, the family head orders mc to never meet seyun again and that seyun will be doing evening patrols with petch, this is something because of their family is a military, government something? that protects the country. mc denies this order and even say he'll go on patrol with seyun.
night patrol happen, nothing much happen. the terrorist group, peste/pestillence something continues to brew their plan.
this terrorist group, peste, are also the ones behind the bank robbery arc.
one night, mc takes a day off for the night duty. seyun and petch are left to go on patrol. petch is going to confess to seyun? but it was stop when an alert came telling that the terrorist group launch their plan. in the middle of the city, a giant winged lion is wrecking havoc. the two goes to respond. meanwhile, mc is in the club of ahnseyoung, they are traning along with the zombie horde. suddenly they also got the alert of the terror attack. they are supposed to handle crowd control of the civilian. mc had a bad feeling, ashnseyoun let mc go fimd seyun.
meanwhile, seyun's family who are the first to respond to the scene gets defeated. seyun's aunt, the predecessor to the goblin ideya gets killed. the family head was about to get killed when seyun and petch arrives and managed to rescue him. unfortunately, the winged lion is just too overpowered. seyun is in a dazed state because of what happened to her family, petch is strong but not enough. seyun, regains composure. she face the winged lion, it wasn't enough. petch takes the ideya of seyun's family head, the imagination creation ideya, it's not enough. when they thought all hope is lost, mc suddenly appears.
seyun gets mad at mc for appearing and asks mc to runaway. mc reject the idea. mc faces the winged lion. mc immediately goes to phase 2. it wasn't enough. mc goes to phase 3 not enough. mc goes phase 4. (i think that's what happened? 3-4 phases? or maybe just 3) when mc goes full berserk, the winged lion became a pin cushion. at this point mc's murder ideya, rose from s rank to ss rank. mc is able to conjure mythical stuffs for him to use. runfortunately, somehow, the murder ideya became some sort of not just bloodlust but also became sadistic. the human priority is also high but still, if provoke, he will go to the nearest target, and the one that provoked mc is the winged lion.
after a bit of flashback to mc's trauma and a bit of the battle scene, mc manages to pin the winged lion to the ground and made a pin cushion out of it from the mythic items mc conjured. the lion is alive but severely beaten and is unable to move. suddenly, rescue/response teams appears. one of them is school doctor who mc respects well. under the effect of the rank ss murder, mc kills the other rescuer and gave the school doctor traumatic memory. the school doctor is alive after this arc btw :) the wing lion died and disappeared at this point btw. seyun appears, mc also gave her a traumatic memory, she's also alive after the arc.
i'm saying traumatic because is just totally psychotic at this point and just very.. mental.
other rescue/response team arrived, mc is still in that rank ss murder state. mc was about to go murderspree when seyun stabs mc at the back.
forgot to mention, the rank ss murder ideya of mc, is something like a double edge mental state. mc wants to kill but he also wants to kill and this paradox of a mental state frees him of something holding him back? or something. so seyun back stabbing mc is very much what he also what he wanted.
fortunately, after seyun stabbed mc, mc was fine and returned to his normal state. unfortunately, what had just happened suddenly came back to mc. mentioned earlier, although mc loses control of himself, he remembers everything that happened. mc goes into a shock.
mc wakes up on a hospital bed. seyun is beside him. before the two could talk more. li xuwin, south korea strongest, briefs mc of what happened. seyun had to leave first. mc is called a disaster class person of the country but despite this he is recognized as a hero. they all thanked mc for what he did.
i stopped here.. so, the title just stopped from pretending as a worthless person and go to clearing my name or something.. the story is nice and all btw :)
stopped at chapter 66, there are still 90 chapters but i think im good here.
