After hanging out with the Body Improvement Club and Telepathy Club more, Mob starts to feel joy like he'd never felt before. One day while he's having fun with them, he gets a call from Reigen, spoiling his fun. Mob asks Reigen to stop summoning him so suddenly, and Reigen just handles the situation in his usual overbearing manner. And because of something very minor, a gap forms between them. Reigen is forced to go on jobs without Mob, forcing him to reexamine himself.
Now that Mob's decided to 
lead such a mundane life,
الآن بعد أن قرّر موب أن يعيش حياة طبيعيّة
Wenn Mob jetzt so ein
ereignisloses Leben gewählt hat,
Como eligió vivir una rutina monótona,
Como ha elegido
la rutina y la monotonía,
T’as plus aucun intérêt
à utiliser notre petit Mob,
Ora che Mob ha deciso
di vivere una vita così ordinaria,
Agora que o Mob decidiu seguir 
uma vida tão mundana,
Смысла использовать Моба, который
выбрал серые будни, уже совсем нет!
