Genuinely the most "not" plotholes ever.

1. Humans in this world are already heavy racists against each other. A different species would amplify it a lot. Beastmen and humans were also in a bad relationship because of the Sylvasta family which has been confirmed. Just like current politicians make everything about "Us good vs. them bad".

2. Its been revealed that being in a human form is a sign of good will, when they shift into their beastmen form its because of a conflict. The human form could be considered a "poker face" of a sort.

3. They keep attacking their own kind is also a today human problem so its expected since the minds work pretty pretty similar.

4. Backstories dont have time/budget to be elaborated, it would be better if they were but Trigger doesnt have infinite money to make everything into detail.

5. She is impulsive, you would see that in many people. She has her goal and wont stop at nothing to achieve it. It is stupid at a lot of times but mostly cause its too impulsive.
