Basically what I think their theme songs are

I know it's been a while but I swear I'm working on it

So here you go

Kuro Tamashi: How Far We've come by Matchbox Twenty

Rin Kazashi: Bubblegum B*tch by MARINA

Jun Nishu Lucky Stars by Lucy Spraggan

Toshiaki Daiki: Welcome to the Black Parade by MCR

Uyeda Shun: Dandelions by Ruth B.

Amy Chika: Burning Pile by Mother Mother

Minami Hoshi: Fallen Leaves by Billy Talent

Sora Sayuri: Colors by Halsey

Robin Oga: House of Memories by P!ATD

Ichigo Hina: Monsters by Timeflies and Katie Sky

Toshino Yu: Monster by STARSET

Moriyo Hana: Change my Clothes by Dream and Alec Benjamin

Yuki Yuudai: Sharp Edges by Linkin Park

Kazuno Kira: Cry Baby by Melanie Martinez

Kana: Boulevard of Broken Dreams by GreenDay

Hirohito Tsutumo: I'm Just a Kid by Simple Plan

Monkomi: Killing Butterflies by Lewis Blissett

I don't have any particular reason why I picked some of these except for like a few (like Rin and Kazuno)

Others I picked via personality or backstory.

Let me know if you can think of a better song for a certain person

Cya in the next one (I'll get Into Code before the end of December hopefully) -Flare
