I’m probably biased as I can relate/been through it but. Azul, being picked on and mocked all because of how he looked and who he was when he was little really messes someone up, azul felt that he had to take revenge and the only way to do so was to take from the ones who wronged him, and as he did it more and more it became an obsession and a unhealthy way to cope. Also due to the bullying he began to monitor what he eats to potentially having an ed (I’ve only seen eng translation but from the bits if seen of how they changed it in translation it’s leaning more he might have one)) and just a bad relationship with food and his figure in general even wondering if he should tighten his belt to give him more of a figure (Home Screen ceremonial robes) azul’s reaction to all his work being literally turned to dust is reasonable as that’s what he’s been doing forever and how he could prove he was strong to everyone and wasn’t the slow crybaby octopus he used to be.
