I think you're talking about Takai. Nishio is the omega. But yes he's increasingly developing alpha features. I imagine after this the dad will be like so what tf are we doing now and him and takai will agree they should test blood samples and see wtf going on. (I hope anyway). Also nervous etf the son is gonna end up encountering. Like what if his own alpha or smthn mutation gets triggered with the heavy pheromones wafting out of the door frame .
WAIT MY BAD IM SO BAD WITH NAME WTF LOL BUT yeah you get it
Yeah he also got taller but for the most part what I think changed the most was his face it got way sharper he used to have way more round features as recent as Vol.3
Am I the only who thinks Takai kun has kinda gotten buff? Like he looks more and more likes an alpha physically and mentally(?) Lol idk if its just me tho
