Tokiya Mikagami 水鏡凍季也

Tokiya is a second year student at Nashikiri High School, and he wields the madogu Ensui ("Dark Water"), a sword that utilizes water to create its blade and is capable of creating and controlling all three states of water (liquid, solid and gas). He is often referred to as by his last name, though his companions have made up nicknames for him, such as "Mi-chan" or "Mi-bo".

Despite the difference in his age in the anime and manga, Tokiya wanted to take Yanagi from Recca because she looks exactly like his sister, Mifuyu Mikagami, who was murdered in front of his eyes when he was young. He uses the Hyomon Ken style which was developed specifically for the Ensui and the Hyoma En (a madogu that also controls water, but focuses more on water in its solid form). Tokiya joins forces with Recca in attempting to rescue Yanagi from Mori Koran's mansion, and he continues to be part of their team throughout the rest of the series.

Tokiya is initially portrayed as callous and aloof; often insulting his teammates' abilities and intelligence. Other characters have often praise Tokiya for his intellect and composure during battle, with some going as far as to say that he might be the strongest Hokage member when it comes to normal battles. Another characteristic of his that makes him stand out among his teammates is the fact that he is more ruthless and cruel than the rest, a fact recognized by both Kurei and Mikoto, who both act as antagonists throughout most of the manga.
