The older brother Mumei serves is Biba Tenshin, leader of the Hunters - a special division dedicated to hunting Kabane. However, while the people praise Biba as a hero, Ikoma does not trust him.
If everyone was strong, 
there'd be no more sadness.
.إن كان الجميع أقوياء فسيختفي الحزن
Wenn alle stark wären,
wäre auch niemand traurig.
Si todos somos fuertes,
no habrá tristeza.
Si todos somos fuertes,
no habrá tristeza.
Si tout le monde était fort,
on serait tous heureux.
Se tutti fossero forti, 
non ci sarebbe più tristezza.
Se todo mundo fosse forte,
não haveria mais tristeza.
Если все мы станем сильными,
больше не будет печалей.
