Place it at the climax of a character edit, just after the confession scene, then follow it with JoJo To Be Continued to freeze the moment on a cliffhanger. For a darker sequence, open with Re:Zero Return by Death before the devotion lands, so the sacrifice sets up the reveal.
About this sound
This seven-second Japanese voice clip is addressed to Dazai, with the speaker saying they have lived until today to die together with him, before a breathy reaction closes it. The solemn delivery and sudden closeness feel melodramatic and absurd, turning devotion into something both romantic and unsettling. It is linked online to Osamu Dazai of Bungou Stray Dogs, whose repeated talk of double suicide makes the line familiar to fans.
