Please don't make some kind of "they proofed they are strong and get recognized" bullshit in the end, I want cosequences and a real reality slap in their faces.
the reality should be that timid girl dead, the 2 fool lost themselves an arm or leg before rescue come
but that gonna be too harsh for this kind of manga
let's say the timid girl crippled
so the remaining two can regret for it
Sister is a useless piece of crap and making her able to copy belamus’ magic just by seeing it once was just a bad attempt at making her useful. (Doesn’t make much sense btw)
