Hey people! In Volume 4, we saw Issei adquiring a jewel of Albion and thus gaining a power (Dividing Gear, that lately becomes in white wyverns).

In Volume 17, Grendel is sealed in a jewel. Why Issei don't adquire that jewel? Why don't put then that jewel on his armor? He would gain a new power... Sure. Perhaps the ability to release little Grendely wyverns.

That bugs me. Really. And so. If I were Issei, then I would had gone to Saji and sure I would had taken a jewel from his new black armor. :E
