Megumi's chat with Nanami is making me think of "yeah, they shouldn't put someone who can summon an Ox or Elephant in basement....."
the only thing he can't summon is tiger, mahoraga and his domain
everything else is fair game (tho ox and elephant ARE at my discretion to not destroy hotel)
the walls are so thin down there he'd be busting right through with his bigger summons lol
ox can charge and just demolish everything in its path
