Star vs. The Forces of Evil/ High School DxD

Summary

Marco Diaz, about two years after Star has returned to Mewni, decides to attend school in Japan, specifically Kuoh Academy. There, Marco will get into many adventures with the High School DxD cast.

Planned Points in the Story

Bring about some point in the story where Star will return and meet the cast, most likely on Marco's birthday

Marco will not change species, nor have any Sacred Gear

Bring about the return of the Monster Arm, this will be explained in greater detail in the character analysis.

Marco will enter the story around the point of the church fight, I am not completely decided on this point.

Character- Marco

Marco will be 15-16.

Marco will be living alone, I will do my best not to explain this.

Marco does not have regular contact with Star.

Abilities

Marco will have his fighting abilities from the show, they alone will not be enough to take on the characters from High School DxD

Marco will be able to speak Japanese, to make things easier.

Marco will have the ability to use, extremely weak, Mewnian magic. It will only be spells that Marco has seen Star use, at a greatly reduced efficiency.

Marco will experience a return of the Monster Arm.

Monster Arm

I intend to have the Monster Arm to be an unconscious fail safe for Marco. The Monster Arm will no longer be isolated to only Marco's right arm and it will be able to be expressed in different ways. The Arm will also no longer be sentient, although a mouth will still appear, somewhere, on his body when it is being used and it will still be a dark influence. Marco will also gain a complete squid-monster transformation later in the story, think of the arm possessing his body.

Problems

I am not a High School DxD fan and lack knowledge on the subject matter. There is also the fact that I will likely abandon the story soon after I start.
