A parody on "anime", animu is a word used to say anime in a mocking or teasing way.
It can be used as an adjective where describing something as "anime" wouldn't sound correct.
It can also be used simply as a replacement for anime, but is only used in a joking way. When used as a noun, it usually is plural, but this is not a rule.
"I like the band 'Gesu no Kiwami Otome', but they might not be animu enough for your weeb tastes."
"Look at me, I enjoy watching all the animu because I'm a Japanophile!"
An animus is a magic user who just speak out his or her command at an object, and the object will act on the animus's command. However, every time an animus uses his or her power, they lose a bit of their soul.
This palace is built on animus powers.
