Review Detail of Rin_Nurnia in World End: The Successor's Contract

Hmm... The storyline was good but I think there are some mistakes like I'm a bit confused with Ava and Uta. Ava is the second sister right? And Uta is the demon? If it is, I suggest you proofread again cause the names placement doesn't seem correct. I'm sorry if I was mistaken...😅
