I'm giving Dina the benefit of a doubt since she only understands her abilities in game mechanics like Lufasu. She never tried to teleport someone's head off.
@Kaarme Most manga don't end when their main story is over and will leave plot points open for new arcs. Maybe the villain was supposed to make a comeback or the manga got canceled before that plot point got used.
@audinue That's partly the point since he played support in the end game and only as powerful as the team so he gets hurt in every battle so far even though he should be way more experienced. His goal is the raiding party but he needs to train them into their roles and learn to trust his team first.
Index has the ideas but Railgun has better character development. Currently, the main idea of the third season can be taken as there isn't just one hero and had Kansaki's character development to kicked it off.
@daime17 I hope the light novel change or explain that in a better way. Like how the monsters can't lie got changed to Cromwell might have felt guilty or pity and decided to save Shizu in this chapter.
