Well then, that makes it all the mroe exciting imo. and since now their enemy can nullify sacred gears, perhaps theam DXD will have to rely on the beings sealed in their sacred gears as opposed to the SG's ability. Cant imagine how powerful Gasper could become. The Truth Ideal was sealed with God's will, so i dont see why another god, presumably less powerful, cant be sealed into a SG too.
