Might be a stupid idea, but what about to speedrun an achievement "Tanuki In The Fog"? I don't think I need to say anything more here.

no please explain, thanks

@Kais there's really not much to explain. On Yamaoka you can find hidden tanukis at the edges of the map, which then explode after you came near them. The timer would need to start at the start of the match and the timer would need to end when the tanuki is fully disappeared.

Would be easy to implement, but it's highly RNG based (just like the glyph categories) and you don't really do much besides running around the edges of the map to find it.
