Review Detail of Poison_Tester in D & O System

Alright the two things I have a problem is story development and character design. MC really showed and shared his power with his "sister" smh. Mostly because if Hermione from the future that's already a big cheat. (She was the greatest witch of their generation) But he decides to help her? What if she turns against him one day? Remember this Hermione is from the future where she died. And she used to live as a only child and probably doesn't see MC as a "brother" so she would most likely kill him. Also MC is too trusting. Ik for a fact if someone like Hermione went through a war and died her "morals" would have dimmed down by a lot. So yeah if mc didn't help Hermione and stop acting so naive I would give this a story a 5/5.
