"I WILL FULFILL MY DUTY! I WON'T LET ANYONE HERE DIE!"

Scene context

Rengoku makes this declaration as a leader confronting a life-or-death battle, asserting absolute responsibility to protect those under his command. With fierce conviction and unwavering resolve, he vows that not a single person in his presence will fall. This statement distills his core principle: a leader's duty is to sacrifice everything to safeguard their comrades.

Character voice

His voice embodies a leader's philosophy: duty supersedes all else, and protecting one's comrades is an inviolable principle that defines his entire character.

Grammar

～を全うする JLPT N2

To fulfill or accomplish completely; to carry through one's duty with absolute commitment. The object marker を combined with 全う (to complete fully) and する creates an emphatic sense of total dedication to a responsibility.

～(させ)ない JLPT N2

Causative negative expressing strong refusal and emphatic denial. Here, 死なせない (won't let die) conveys absolute determination to prevent harm: 'I will not allow anyone to die.' This is stronger than the simple negative 死なない.
