MECHATU-A Take the Hero Show to K Arena Yokohama for First Solo Live
A unit built around game and anime covers filled a Yokohama arena on the strength of an album that moved 326,000 copies in its first week, which is the scale Nijisanji is now asking its smaller units to carry.

The Nijisanji VTuber unit MECHATU-A held its first solo live, "Over Drive!", at K Arena Yokohama on October 10, 2026. The show opened with a hero-show framing: an opening movie, a staged explosion, and the villain KOZAKA-C interrupting the MC segment. Members performed solo and trio covers between group songs, and the first mini album "On-Deck!" had topped Billboard Japan's Top Albums Sales chart with 326,000 first-week copies.
The set leaned on the group's gaming habits. Saeki Ittetsu sang Alex's character song from Street Fighter 6, "GO! ALEX! ~Kibou Tanjou~", with the character on the center monitor and a side-scrolling fight between Saeki and a kuroko playing underneath. The unit has several members who play the game often, and the crowd responded to the reference.
Elsewhere the show mixed covers with original tracks: Usami Rito on Vaundy's "Gyakkou -replica-", Koyanagi Rou rapping over "Yofuke no Paraded", and a trio of Hihachi Mana, Hoshirube Sho and Koyanagi on "Hachi -HACHI-". Inohara Rai closed his segment with Official Hige Dandism's "No Doubt".
