Iruma and Lead end up being trained by Robin's relative, Barbatos Bachiko. Bachiko is very skilled and was personally asked by Sullivan to assist Robin with tutoring the kids. They were supposed to have a rather hard training schedule... but all Bachiko asks them to do is random errands. Lead has had enough of that and goes back to Robin. Iruma is left frustrated and alone. He learns that Asmodeus and Clara have been training and decides to take matters into his own hands!
That's basically how my 
training's been going every day!
!هكذا كان يجري تدريبي كل يوم
Ese es mi entrenamiento diario.
Ese es mi entrenamiento diario.
C’est mon entraînement quotidien !
E il mio addestramento 
procede quotidianamente così!
И вот так вот я 
каждый день тренируюсь!
