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.
You're acting rather weird 
today, Shikishima-kun.
تتصرف بغرابة شديدة اليوم يا شيكيشيما-كن
Du bist heute echt komisch.
Estás muy raro hoy.
Estás muy raro hoy.
Je te trouve bizarre, aujourd’hui.
Oggi ti stai comportando
 in maniera strana, Shikishima.
Você está muito estranho
hoje, Shikishima-kun.
Слушай, Сикисима, 
ты странно себя ведёшь.
