Tbh I'd just fucking dissapear if I were Hikari. Literally. Go back home in the midst of the rain, pack up some stuff, ask parents for some $$$ buy a new mobile chip, notify my parents about it, smash the old one with the sole of the shoe, and just pick the first train that came and ride it to the last stop. And just stay there for as long as it's possible. No explanations, nothing, to nobody. Not that they would've noticed when I'm gone lol, up until that dude fastened his belt back I'd already be on the train. They'd never see me again in their fucking lives, wondering why or searching shit won't bring me back.
I'd also get a haircut and dye my hair or smth, don't wanna be spotted.
That's my headcanon, rant over. This chapter did things to me.
