Previously on Spirit Hero the evil Riba has attacked team Urameshi and began a fight to which Riba was about to finish until Izuku undergo a demonic transformation-

Demon Izuku: Riba, get ready for a world of pain!

Riba: It is you who shall be in pain!

Both dash forward and meet at the center of the ring. Riba readies his sword and-

Riba leaps up and tries to slash Izuku, but-

Riba slashes down with his blade only for Izuku to catch and break it with his hands-

Riba: That blade was my father's!

Demon Izu: Well, I guess you are a disappointment to his name.

Riba leaps back and screams-

Riba: I will end you! (Dashes forward)

Demon Izu: You'll die trying. (Dashes forward)

They reel their heads back-

Demon Izu grabs both of Riba's hands and heads butt him and began to push him back-

Demon Izuku stopped punching him and Riba fell on his knees-

Demon Izu: If you ever hurt my friends on anyone else...(Gets to his face).I will kill you (Walks Away)

Riba: You have all this power yet you are still weak. (Stands up slowly) I guess that means I can keep coming after your friends again, again, again, again, and-

Yusuke and the others look upon Izuku with shock that he just killed someone. Izuku drops the head and all of his Demon seep into his body. He falls, but is caught by Modus-

Modeus: (Thoughts) Izuku you are something else~

After the whole thing Koto declared this round of the dark tournament over and thanked Izuku for saving her. Izuku is now in bed resting wondering if that was caused by elaine the angel/demon hybrid-

Modeus: Hey Izu~

Izuku: Hey Modeuuuuuuuuuu

Modeus: Like what you see~

Izuku: Why are you here?

Modeus: Well, remember how you asked me and Hiei about what it's like to be a demon?~ (Crawls on bed toward Izuku) So, I thought I could get something in return~.

Izuku: Ok, maybe we should (Mouth Covered)

Modeus: Face it sexy, I have something you need and sure as shooting have something I want. So, be a good little demon and Mama will give you a cookie~

Izuku: (Smirks) I guess I could play a little

Modues: I'll take that as a yes~
