Dandadan: Hollow Stray
Rei Kazehaya, a reclusive high schooler, is thrust into the world of Dandadan after discovering a Hollow mask hidden among his late father's belongings. The mask fuses with him, granting the powers of Primera Espada Coyote Starrk—twin Cero-firing pistols and a Hollow form born from deep loneliness.
Choosing to remain in the shadows, Rei silently watches Momo and Okarun’s battles with aliens and yokai. But when psychic Momo senses his sorrowful energy, and he steps in to protect Aira from the Acrobatic Silky, his quiet existence ends.
As Rei joins the main cast, he struggles to contain the Hollow within, forge fragile bonds, and face the very death aspect that fuels his power—loneliness.
