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!
I was enjoying the good life so much 
that I forgot about your training.
.كنت أستمتع بحياتي المترفة لدرجة أنني نسيت بشأن تدريبك
Die letzten Tage waren so gemütlich,
Estaba disfrutando tanto
que había olvidado tu entrenamiento.
Estaba disfrutando tanto
que había olvidado tu entrenamiento.
J’avoue, j’ai merdé.
Mi stavo godendo così tanto la pacchia
che mi sono dimenticata del tuo addestramento.
Ah, sobre isso...
Ты уж прости меня, парень!
