Just gonna leave this right herrrrr'~
IN MY HEADCANON, ARAI'S ELDEST BROTHER (Keisuke) SACRIFICES HIMSELF TO BRING BACK NEJI (and others who have died, actually uhuhuu) USING A FORBIDDEN JUTSU THAT TRADES A LIFE FOR SOMETHING EQUALLY AS VALUABLE: In Keisuke's case, another life. Of course, Arai tried to stop Keisuke from doing so, not wanting to lose her brother, but Keisuke goes through with it, hoping that this deed will also cleanse him of his sins so that he can go up and join his mother in paradise ; u ;
And NO, I didn't kill off Keisuke just to get Neji back (in my headcanon). Keisuke was doomed from the start, like, 10 years ago when I made him lolol. Now that Naruto is finally over, everyone's roles (my OCs, I mean) are completely solidified to not get too crazy. I just couldn't let go of Neji's death, though.
Nejai uhuhuhuuu~
Probably gonna remain sketchy because I don't have the time to line it properly :U
Doop doop doop, that's all I've got for you with this. Colored (but not lined) version is up nexttt.
