Akiba's Trip The Animation

Tamotsu's shopping trip to Akihabara with his sister Niwaka becomes a fight for survival when creatures possessing human hosts attack. The mysterious Matome saves him after a near-fatal injury, but her power comes with a consequence: he can no longer leave the district.

He joins Matome and her allies against the intruders, whose strength fails when their bodies are exposed to air. Part-time work and favorite hobbies now share space with increasingly strange battles. Protecting the neighborhood he loves also means discovering what he has become and why its enemies are gathering.
