Once I heard what would be involved to get the items and the RNG that it would take, I resolved to not even start the quest. I didn't have much interest in Yokai, but this event would have made me needlessly angry, just as every other Atma-like FATE grind has done. Obsessive FATE grinding combined with RNG is this game at its worst, and I did not want to convey to the bean counters that I "enjoyed" the yokai event by completing it.
The next time Level 5 comes out with a game that sounds fun at first, I'll remember this, and their twisted idea of "fun".
