The Shield Hero now an Average Tutor!?

Chapter 1: I'm Not the Shield Hero?

"Onii~chan! wake up!" 

A voice I hear? It sounded like a little girl... But for some reason I was able to recognized who it was. At the same time it felt like a stranger to me. What the hell happened to me?

Additionally my head felt like shit. Almost as if I was blasted by Fitoria's magic again. Then again, compare to most enemies I've faced that are able to pierce my defense, Fitoria the Filolial Queen was one of them.

"Onii~Chan! How long are you planning to sleep? Get up already!" The sounded little girl was desperate on having me up, "Come on, I even made breakfast!"

I couldn't continue to ignore the girl so I open my eyes and got up. I felt a little tired though as a yawn. 

As my vision began to be visible this little girl. That's right, She's my little sister Raiha. What?

How do I know that? Of top of that, this does not feel like me at all... Where are Raphtalia? Filo and Rishia at? This wasn't making any sense for me.

My mind is suddenly mixed up with another as it seems like its merging together. Okay, I think I understand about this situation. So after supposedly returning to Melromarc from Kizuna's world I some how got myself wrapped up in this world. Another note is I'm whole different person now.

This body, is named Fuutaro Uesugi. Same age as that justice wannabe Itsuki Kawasumi the Bow Hero, seventeen years old and a second year high school student. 

Honestly, I don't know how I should be feeling about this sudden change. The old me would have been relieved that I got out of that hell hole of a world. But now there are other stuff that I haven't fulfilled yet after that whole Kyo incident. With the defeat of that bastard, we retrieved back the Spirit Tortoises' soul back.

I don't even know if I'll be able to come back to that world. Plus is even possible for a Cardinal Hero to suddenly transport its soul to another from a totally different world like this one?
