Shirou Yusa

"Burn in hell, Vampire! Sing your Sieg Heils there forever!”"

- Shirou Yusa, killing Wilhelm Ehrenberg

Shirou Yusa is a major character in the anime and visual novel Dies Irae, and the best friend of protagonist Ren Fujii in spite of their clashing personalities. Shirou can be described as a rebellious and aggressive delinquent who is highly intelligent in spite of his nature, in contrast to the more level-headed Ren. At the beginning of the visual novel, Shirou and Ren get into a fight that lands both of of them in hospital. While Ren spends an extended period of time in hospital, Shirou leaves early and meets up with Eri Honjou, a girl with a similar personality to his own while wandering the streets of Suwahara. The two of them have a narrow escape from the nigh-immortal Nazi occultist organization Longinus Dreizen Orden, who are in Suwahara to conduct a ritual to revive their leader, Reinhard Heydrich, and ascend him to godhood. Since then, Eri and Shirou dedicate themselves to hunting the LDO.

Shirou meets up with Ren after he also encounters the LDO, at which point the plots of the visual novel branch off depending on the players actions, however, in multiple routes, Shirou engages in combat with Wilhelm Ehrenberg, a member of the LDO with vampire-like powers on multiple occasions before finally defeating him, most impressively in Kasumi’s route, where he kills him using conventional weapons, along with discovering and exploiting Ehrenberg’s weaknesses, while possessing no superhuman powers of his own, beyond enhanced strength and pain tolerance.
