It would be Ivudot! He already has a page under the name Ivu which was his previous name, seeing how he participated in the Bomberman cover of Ai Kotoba iii instead of "Ivu". I haven't really listen to his songs too much outside of the Bomberman covers but from the cover of the Osomatsusan song and Ai Kotoba iii, his voice changed a lot! Hope this helps!
I'll move further discussion to the Ivu. page I guess? Or maybe a new ivudot page should be made seeing as he's using this as his new identity? Edit: Or maybe not. the wiki discussion feature seems pretty bad.
