Brothers' Duel

What brothers do best.

Koji and Yoshi have first met when the succubus named Marian rebirthed aborted children for her means of conquering the world, and she became drawn to Montana upon sensing another demonic entity: Koji himself.
Upon Marian's defeat, Koji lamented nearly destroying the youngster by destroying that red gem embedded in his throat which served as the link between the Children Of The Grave and Marian. With the boy's lifeforce quickly fading, Koji attempted to transfer some of his energy into the dying child, hoping to mend the gaping hole in his throat and restoring life. Unfortunately this left Koji drained as he was unable to complete the transfer. Erin (Koji's mother), took the boy to the emergency clinic to stitch him up, then took him in upon realizing that this child was indeed the same boy who would have been her first born nearly 14 years before, and gave him the name Yoshi.
Ever since, the Hanyo brothers have been inseparable, seeing that they are evenly matched in power. Yoshi, however, has much to learn when compared to Koji's experience.
