Akuten (a Touhou LW original) refers to bad weather, particularly violent storms. The following is an excerpt about the bearer of this temperament from M's report. "From what I can tell by reading the notes scattered about Reimaden, the evil spirit seems to have some kind of relationship with the shrine maiden's family. But I don't think she hates them. I don't know why she wants to destroy the world, but that shrine seems to be the only thing that is stopping her." Mima desires to become more powerful than the Hakurei bloodline and take revenge against the entire world (strong against Wood Phase and Sun Essence).

The ability of Mima from the isolated world (a Touhou LW original). All information about this ability is shrouded in mystery. The following is an excerpt about the bearer of this ability from M's report. "I-I'm scared... But if I show that I'm scared, I'm sure that'll attract more of those strange presences. This evil spirit must have a really strong grudge if she's here in this Reimaden place to prepare for her resurrection and plot her revenge... I hope this sinister atmosphere won't affect my phantom guide. You won't suddenly turn on me, will you, little phantom?!" "..." "P-Please say something..." "..." "Oh, right. I forgot you can't speak. Anyway, it's kinda strange how this evil spirit is able to leave such detailed records while waiting to resurrect. Or maybe she has a servant or something who writes them for her. I guess it would make sense if such a powerful spirit could remain asleep while telepathically dictating her words to a servant or directly projecting her thoughts onto paper with thoughtography. Though it'd be pretty scary to actually witness such a thing. All right. I'm gonna take as many of these notes as I can carry, and then we can get out of here... Hey, wait! Don't go without me, little phantom! I'll grab your tail!"
