Tokyo Underground

Beneath Tokyo lies a sprawling, little-known realm called the Underground, home to “Elemental Users” who can command powers such as fire, water, lightning, magnetism, and freezing. This hidden world operates beyond the surface city’s awareness, shaped by extraordinary abilities and the people who wield them.

Rumina Asagi and his best friend Ginnosuke Isuzu are ordinary first-year high school students—until a chance encounter with Chelsea Rorec, a Gravity User, and Ruri Sarasa, the Miko of Life, pulls them into the Underground’s conflicts and wonders. What begins as an unexpected meeting quickly turns their everyday routine into a high-stakes journey of action, discovery, and romance.
