ITT: MCs that changed their Hair style.
Does Naruto count or maybe he just has thinning hair? Male MCs sporting a new 'do seems pretty rare.
Because the anime artstyle is specifically used to be as quick and low-effort as possible and thus has a lot of issues like sameface and the inability to tell characters apart without resorting to hair styles and colour.
Because hair style is usually one of the most recognizable feature of main characters.
No love for wendy? only good thing about FT.
