mkmk this is what i know. mahito (the patch face) was beaten by itadori and his "best friend" todo. but ran away to geto, since he was about to die. since everyone is weak including itadori, geto wanted to take advantage of that. and starting fighting. but the second-years and the others came to help. but some of their shots and hits weren't working. thats when the older brother (of those 3 curses) came. The older brother is keep on having vison of itadori with his younger brothers (the 2 other curses that dead.) so he believes that itadori is his other brother. but we dont know at all. it is possible he is, since we dont know his parents at all. and now people itadori he might be a half curse.
sorry if this didnt make sense, im so lasy to make it perfect. <33! new chapter coming in the 1-17-21 btww!
.....but thats not geto thats noritoshi kamo. The point of this chap is that noritoshi is the (possesed)father of choso who impregnated his mother with curses,basically making choso half/human half/curse. We deadass just found out who choso's parents are. Geto is not Geto. Its Noritoshi possesing geto's brain. Think of the movie Get Out when imagining these two co-existing. As for yuuji's parents,the author said that he will first introduce in the later future his dad,then his mom but he is unsure of when will she be introduced. They will not appear at the same time,that is for sure.
can someone explain to me I'm sorry because I'm really stupid ╥﹏╥
