Ritsu is attacked by students taking on strange shapes, but Satake Shogo saves him with a giant handgun.
Ritsu is taken aback by the sight of him relentlessly shooting students, but he comes to realize that other people can't see the giant gun or the transformed students.
Lost and confused, Ritsu returns to his home where he's greeted by his Mother who's now covered in static and repeating the same exact lines.
Don't turn around, your home 
is here, isn't it? Right?
لا تستدر، فموطنك هنا، أليس كذلك؟ صحيح؟
Was passt dir denn nicht?
No te des vuelta,
tu casa está aquí, ¿no es así?
No te des la vuelta,
tu casa está aquí, ¿no? ¿No es así?
Qu’est-ce qui te déplaît ?
Non voltare le spalle, la tua casa è qui, no?
Não dê a volta, seu lar é aqui, não é?
Не оглядывайся. Тебе всё равно там 
не было места. Правда же?
