UQ Holder!

Touta Konoe grows up in a quiet rural town, dreaming of something beyond his ordinary days. That routine is shattered when his mentor, Yukihime, reveals she’s a vampire—and after she saves him from a fatal injury, Touta finds himself transformed into an immortal.

With his long-held desire to see the wider world finally within reach, Touta sets his sights on Amanomihashira, a towering structure said to rise all the way into outer space. His journey draws him into UQ Holder, a hidden organization made up of immortals like himself, where new allies and guidance help shape the path ahead through a world of magic and danger.
