Suggested by Sonic Erishkegal once fought the Living Tribunal and was a cosmic force to be reckoned with. She has basic super strength, energy blasts and the like. Still, I wouldn’t say that she is going to be able to take down Shiho in a close quarters fight. Shiho may lag behind some of the other characters in Seraph of the End but he has worked on his speed and power. She will have a tough time getting past his twin coffins and doesn’t have the combat speed to stay ahead of them for long. Shiho wins.
Yuichiro is back and it’s time for him to take down another comrade. Shiho talks a really good game and seems to think that he carries a lot of influence within the group, but his abilities aren’t all that impressive. As it stands, he wouldn’t last a minute against any of the real vampires and that’s a bit of a problem since Yuichiro is a demonic being at this point. That may not be the same as being a vampire, but it is just as dangerous. Yuichiro wins.
Levi is very fast and considering that he’s only human, he’s pretty impressive. That being said, Shiho finally learned how to use his demon’s power, which has increased his attack power and speed. His coffin ability is anything but impressive at the moment, but it’ll probably have some nifty feature at some point. Either way, Shiho can definitely defeat Levi in a close quarters fight and that essentially nullifies all of Levi’s options. Shiho wins.
