The Anime Lad
Hell's Gate appeared in Tokyo ten years ago. Psychic agents emerged at the same time, and rival organizations began competing to unlock the zone's mysteries. Hei is one of the most powerful of those agents and works beside Yin. Tokyo has therefore added paranormal espionage to its civic concerns. The agencies appear unlikely to share notes.
Super Eyepatch Fox
Ten years after Hell's Gate appears in Tokyo, psychic agents work for rival organizations seeking its secrets. Hei is among the most powerful and operates beside Yin. The setup treats paranormal ability as part of a covert contest rather than public heroism. Every agency wants access to the same impossible mystery.
Gigguku
Hell's Gate appears in Tokyo, psychic agents emerge with it, and suddenly the whole city sits inside a supernatural contest! Hei is one of the most powerful operatives. Yin works beside him while rival agencies push toward the same mystery. I love how the premise turns extraordinary abilities into espionage pressure instead of a public parade of heroes.
Father's Basement
The lore is deliberately opaque, and the premise offers a large mystery before much orientation. Hell's Gate appeared in Tokyo ten years ago alongside psychic agents. Hei and Yin now work for one of several rival agencies competing to unlock its secrets. The institutional contest gives the powers useful pressure and keeps the setup closer to espionage than straightforward heroics.
