The Telepathy Club is told that they are going to be shut down by the student council due to lack of members. It was then that one of the members, Inukawa, thought of possibly getting Mob to join. However, Mob gets a call from Reigen about taking care of an incident at Highso Girls' Academy...
And Mob was spending that 
precious time working as
وكان موب يقضي تلك الفترة الثّمينة وهو يعمل
Und Mob verbrachte diese
kostbare Zeit als Assistent
Mob pasaba esa importante
etapa de la vida
Mob pasaba ese importante
momento de la vida
Mob, lui, passait
son précieux temps à travailler
Mob stava impiegando questo tempo prezioso
Mob passava o seu precioso 
tempo no trabalho
А Моб тратил драгоценное время на работу
ассистентом экзорциста за триста иен в час.
