Compile Heart has a crossover from Namco Bandai in Hyperdimension Neptunia Victory. While they couldn’t get a company character, they have a Tekken specific guest. Introducing Tekken-chan.
Tekken-chan timidly introduces herself and says she’s not Tekken producer Katsuhiro Harada. Tekken-chan appears to be upcoming DLC like other game developer mascot characters CyberConnect2, Falcom, Broccoli, MarvelousAQL, and Mages.
