From a notebook to Infinity Castle

Mamoru Miyano is a Japanese actor and singer whose voice roles include Light Yagami in the Death Note anime and Doma in Demon Slayer: Kimetsu no Yaiba.

In Death Note, Miyano voices a student who finds a notebook with lethal power and enters a battle of wits with the detective L. The role follows Light as his idea of justice becomes bound to the identity he creates as Kira.

In Demon Slayer: Kimetsu no Yaiba Infinity Castle, he returns as Doma, an upper-rank demon whose smiling manner conceals a formidable opponent. His confrontation with Shinobu connects the battle to her family’s loss. The film list below reflects titles on FLM.RED, rather than his complete credits.
