Mika hadn't lied exactly, but he hadn't told her the whole truth either.
That final wish she had made...it had pushed him far beyond what he was comfortable doing. He'd overextended himself, not in the ordinary "I'm a bit tired" sense, but in a way that scraped at the edges of his own limits.
To understand why, one needed to know something about the worlds, realms, rifts, drifts, that existed out there.
Every single drift a Blessed, or any other capable traveler, might enter was classified by danger level, ranked from F-class at the very bottom all the way to SS+ class, which was supposed to represent the most extreme level of difficulty.
These rankings were determined by countless factors: the number of friendly entities in the realm, the richness of resources, the total size of the realm, the number and strength of cursed beings lurking there, environmental hazards, and much more.
