Keine's ability is explained uh somewhere. I can't remember where (EDIT: PMiSS plus supporting material). It is for the most part an ability of illusion.
History, in essence, is the collection of events from the point of view of whoever is writing down these events. The recollection of history is the understanding of these events learned from the history previously written down.
Keine's ability as a hakutaku is that she is the history-writer. She writes down the history of people, places, events, and the affected parties "learn" of this history, and as such believe this is what really happened. However, this doesn't affect their previous knowledge, merely what they will learn. Keine's human form devours history, in that she can remove history that has been written down. Because she transforms every full moon, Keine can reliably delete history and then rewrite it within the span of a month, or write down history and then delete it as she wishes. In IN, she hides the human village's existence by deleting its history in order to defend it from potential threats. By the Extra stage, she rewrites this history, and the human village appears again.
I think it's also clear that this ability doesn't come into play during Spell Card duels. She needs to actually write it down, which iirc is said to be done furiously the one night she can.
Seiga is a hermit. She was previously a human. She uses forbidden arts, and her pin is all that enables her to pass through walls. She has no inherent ability.
I helped write the article on Yuugi's powers for the wiki, so copypaste time.
Anomalies, strength, disorder, and spirits (怪力乱神,
kai-ryoku-ran-shin) is a metaphor for unexplainable phenomena that originates from the Analects of Confucius, where one of his disciples said "the Master never talked of anomalies, strength, disorder, or spirits." (子不語怪力亂神) Furthermore, Yuugi's title is "the so-called unexplainable phenomenon".
More accurately, Confucius did not talk about unnatural things (
怪異, strangeness), mysterious powers (勇
力, courage), things contrary to reason (悖
乱, devious rebellion), and strange things related to god (鬼
神, fierce god). In other words, strangeness (怪異), courage (勇力), devious rebellion (悖乱), and fierce god (鬼神) are why 怪力乱神 is referred to as "anomalies, strength, disorder, and spirits." It is appropriately unclear what exactly this ability allows Yuugi to do, since the ability itself is a metaphor for things that cannot be explained.
Her very name, Yuugi (勇儀), might have come from the courage (勇力) that is represented as "strength" in "anomalies, strength, disorder, and spirits."
Her title is 話られる怪力乱神, or "the so-called" unexplainable phenomenon/anomaliesstrengthdisetc. This does little in explaining the ability, but it should be clear that her ability is not meant to be an actual ability, merely an additional link to the Confucius thread present throughout her character profile.
Important:
She does not actually manipulate or cause unexplained/supernatural phenomena. This was a huge misconception that stemmed from the translation, and was essentially the main reason why the Ability subsection explaining the phrase was created. 怪力乱神
を持つ itself just means "to have", "hold" or "possess". It's currently translated as "wield". No other character ability uses this wording, and is why I
am going to go object just objected to the translation in the SoPM article.
