@desaurido :
What's makes you sure that Diina is on the MC's side? Is it when she prevented the MC to listen to highly important informations about the world and the goddess? Or when she hide previous informations? Or when she attacked MC?
And it really bother me that the MC doesn't question Diina about this move (and doesn't reprimend the robot for closing the discutions).
It was more than obvious that the demon lord wasn't aggressive toward MC.
The explanation "we attacked him to save you" just doesn't work.
The follower's idiocy and the MC being slow is bothersome, but Diina is the worse of all.
