There's a lot of different kinds of blues though?? This girl's complex is all in her own head.
As far back as 2011 I remember Cure Marine breaking all the tropes I associated with blue magical girls. She was a super loud gag character, not a shred of coolness to her.
Oh no that line he says to Chako about her not being special anymore...
She's now on the same level as everyone else manipulating him...
That aside tho, the author did really well in drawing Chako's body! It's a really realistic drawing of someone who's heavier, which I don't see done well...
