RE:Zero: Are Roswaal and Subaru the same?

No, Subaru and Roswaal are different people.

RE:Zero Emilia’s Backstory

Emilia’s back story is average storytelling at best.

Hange is right to ask, why did you just say fight twice Eren?

The lines are blurred since he is a child in this world, but has the mind of an adult.

The bets are made, Senku is going all in with Gen on selling a big lie and a single music track.

Depends. If you want horny meets Isekai then Moshuko Tensei is worth watching, if not this might be one to skip.

The curtains are being pulled open on Emilia’s past.
