no restrictions who wins
Ban and the Raitei can get by this match thanks to superior speed and hax. While not as durable and destructive as Inu and Sessy, the two dog demons lack a means of fending off Ban and Ginji's hax abilities from literally ripping one's soul out of their body (Ginji) to outright erasing the enemy from existence (Ban).
@shinjihirako123: They still won't probably win due to team 2 powers. But InuYasha and Sesshomaru have a nice set of hax abilities them self. Sesshomaru alone has the power to kill team two with bakuseiga. Like InuYasha could take them out with Meidou Zangetsuha. These are only based off of the assumption that these two would hit the getbackers first. InuYasha and Sesshomaru's attacks are good, and have enough power to kill team 2 in one move,but again as I've said it's an iffy situation.
Both can kill each other pretty easily, but team 2 has better advantages.
