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.
My mind has been feeling 
funny since that commotion.
ينتابني إحساس غريب في عقلي
منذ تلك الجلبة
Seit diesem Aufruhr fühlt sich
mein Kopf ganz komisch an.
Mi mente se siente rara
desde esa conmoción.
Mi mente está algo rara
desde esa conmoción.
Depuis la cérémonie,
tout est confus dans mon esprit…
La mia mente gioca strani scherzi,
dal momento del trambusto.
A minha cabeça está esquisita
desde aquele tumulto.
С того самого момента 
мой разум будто сам не свой.
