In This AU, Izuku is Katsuki's Guardian Angel. They never met each other.

This was supposed to be another normal lesson.

Yet,it didn't turn out like that.

”Guardian Angels..real or myth?” Aizawa suddently asked his class sharply,his eyes darting amidst each of his students,who sported puzzled looks.

”Myth,” The hotheaded blonde, Katsuki, interjects and replies flatly, like it's the most obvious thing ever.

Aizawa's expression turns solemn and nonchalant, and he gestures Katsuki to not move.

He then throws a knife in his direction.

Katsuki didn't expect that. His teacher throwing a knife at him? For a moment panic stirred within him, and adrenaline pulsed through a little too late—

yet, he wasn't injured. He looked around, and once he caught sight of a light emitting from something or someone, he froze and gaped.

There was a whole— angel, or something, which had taken the hit with his right extended wing,which was now tinting the gorgeous ivory white a crimson red.

The guardian angel seemed unphased, sharply looking at Aizawa as a warning to not do that again.

Aizawa kept a nonchalant expression,having expected this.

Everyone's eyes were on the creature- the Guardian Angel with mossy green hair and heavenly clothing (pun intended).

This was also Katsuki's Guardian Angel.
