Tetsuya Yuichi is a Japanese CVVC voicebank created by kotozakichaos, who also provides his voice. The voicebank has an androgynous tone, as the character is meant to be transmasculine, like his voice provider. He has 2 appends, SACCHARINE and SOVEREIGN, alongside his regular voicebank, STANDARD. His voicebank works best with just about any song. He also has addons for English singing, such as L consonant, english rhotic r, nm/ng consonant and s/sh consonant, with trilled R only for his SOVEREIGN append.
