What do you think the earthquakes are about?
Dragons! What more to say? Ukyakyakya.
Or not . There might be something monstrous that has been sleeping underneath the school (a dragon per se) and it is slowing waking up from its beauty sleep. How should I know? This is a weak hypothesis based on nothing more than mere earthquakes and guesses.
Do you think anyone is behaving suspiciously? Who?
I don't 'think', I know.
What do you think happened to the headmaster?
I would've laughed my butt off if he really had been eaten by a dragon.
What or who do you want to know more about?
The sword of the Kifel dorm master ~. Why?
Since I find it more interesting than the headmaster himself. Ukyakyakyakya. Weapons over humans you ask? Well. *smirk*
That sword is a demon sword that is always attached to Ida, so it seems. However, when I saw Ida in the forest there was no sword along with her... That sword might have a connection to this case.
It could also be that you forgot to draw the sword, or that it is not always attached to her, (or I remembered wrong) Lol. XD Let's see the continuation, it is all so very exciting~
