[Blue Lock] A Succubus Can Live Independently in a Sports Anime!

(Warning: I don't know anything about football, so please point out any mistakes!

All-character pairing direction, but the ending has no CP. The protagonist is naive but a bitch. Cross-dressing warning!

The protagonist is beautiful, strong, and overpowered. He won't steal screen time from Isagi; that's not his goal. But since he's involved in the main plot, he may take screen time from some other characters. The one losing screen time here is a random character from Team Y. Sorry about that! (bows deeply)

There are some personal additions, but I'll stick to the original as much as possible. Out-of-character warning.

Here's the blurb:

Nagi Seishiro stared at the magic circle in a manga that could turn people into koalas, lost in thought. But since he was too lazy to do anything himself, he decided to get Mikage Reo to "help."

Mikage Reo looked at the magic circle he'd made all by himself and said in an amused, child-caring tone, "There, all done. Now..."

A fierce wind began to blow, and a flash of white light appeared!

Mikage Reo felt the scientific worldview he'd built up over years of study collapse in an instant. Good grief, where did this naked girl with long hair sprawled across the ground come from?!

Nagi Seishiro only said, "The magic circle failed..."

Is that really the point?!!!!!

Mikage Yuyu leapt at Mikage Reo the moment she saw him, completely unconcerned that she was naked. She happily rubbed her cheek against his. "Master~"

Mikage Reo could only feel exhausted. And what was that thing in his abdomen?!!!!
