Sweet, it's back! Did not see Kouma swearing himself to Tsukune, but he did make a good choice. Tsukune is now officially the kid with the leash.
Also, Tsukune is now immune or at least resistant to Saffron as well, isn't he? And part of Richard's arsenal! I can just imagine Richard throwing fireballs at Tsukune, but every time he forgets Tsukune is immune to fire and begins to think Tsukune is immortal, thus spreading exaggerated rumors of Tsukune's powers and species.
Also, a funny thought occurs to me. Tsukune is now going to be personally calling for every little brush fire because fire no longer harms him. He is now responsible for organizing a fire fighting committee on the side to deal with rampant property damage.
