Seina Yamada has been waiting so long to return to his home, Earth.
But so much has changed; his sister is engaged to Kiriko's brother Kai,
and his parents' old store is now a huge mall.
Furthermore, he is to stay at Kiriko's mother's house...
How overkill can you be?
إلى أيّ درجة تُبالغ؟

Eso es exagerado.
Il y a des limites à ne pas franchir !

Capisco volere potenza di fuoco, 
ma dev'esserci un limite.
Mesmo um poder de batalha
excessivo tem seus limites.
Любая сила не безгранична.
