There was no way of stopping her in my opinion.
But Dimitri taught her how to summon a demon only because Lewein gave her authorization （￣へ￣）
Different races(?) have different standards. While she believed she's a child and shouldn't do anything dangerous, the others knew she was gonna do it anyways.
Hello? Yes? Is there someone with common sense here? If Sasha is feeling insecure because she doesn't have strength, the solution isn't to risk her life for her to gain strength, but to reassure her and make her feel safe.
Also, I know some kids can be very intelligent, but that's not Sasha's case. So how come MC can't win an argument against a literal child??? There are so many things she could have said but she just left defeated?! It's like she's a child in an adult's body, so her brain isn't fully developed either.
Anyway, I am extremely annoyed at MC's lack of basic intelligence.
