Everyone has a Guardian angel, and some of them wouldn't see that, but Kazuha on the other hand, prince of Inazuma could, including his.

But, instead of a guardian angel..

"Why do I have a demon by my side instead?!" Kazuha sighs, looking at the demon standing beside him, instead of having a devilish or demonic appearance, it's surprisingly a pretty attractive taller male with horns and tail, he could've shown his wings but he isn't for now, who's currently grinning at Kazuha.
