Akito and Mimane have joined the troubleshooters office, and will be helping Kazuya and his friends with exorcising troublesome amasogi. The only problem is that they're also secretly part of the group that has been causing amasogi incidents!
Four at once strikes me as odd.
.أربعة في آن واحد حدثٌ غريب
Vier auf einmal sieht man nicht oft.
Cuatro a la vez me parece extraño.
Cuatro a la vez me parece raro.
C’est rare qu’ils soient plusieurs.
È piuttosto strano che siano quattro, tutti insieme.
Quatro de uma vez é estranho.
Четверо одновременно — большая редкость.
