Tatsuya

this is Hachi-Tatsuyashinjiro, if his name sounds similar to another it should!
Tatsuya is the dark voice inside of Shinjiro's head, and the one whose power is used when Shinjiro goes into god mode

he may look innocent enough but don't trust him so easily,
one wrong step and he'll kill you in a heartbeat
due to him getting so easily offended his father, Kyron, chained him within Shinjiro's mind,
but due to the extreme guilt that shinjiro had experience has his chains started loosening to call upon his powers once more!
