Boruto, Shikadai and Mitsuki arrive at the location they are told to go to by Shino. They notice their teacher is acting different than he usually does— and Shino suddenly attacks them! Shino belongs to the Aburame clan, a clan of Insect Users. He unleashes a swarm of Parasitic Insects. Boruto and the others can't match the skill of someone who's a jonin. But even in this situation, Mitsuki remains calm and coldly stares at Shino.
It's a waste of time trying to
teach you kids.
محاولة تعليمكم هي مجرّد مضيعةٍ للوقت يا فتيان
Egal, wie sehr ich euch diszipliniere,
es ist vergebene Liebesmüh.
No sirve de nada intentar enseñarles.
No sirve de nada intentar enseñaros.
Ormai non ha più senso insegnarvi nulla.
É perda de tempo tentar educá-los.
Пытаться чему-то вас научить — 
пустая трата времени.
