If you're trying to use animu magick to summon your favorite character, maybe you should use these animu magickal correspondences I've devised.
Aiko: earth, north, winter
Pachira: water, west, autumn
Liru: air, east, spring
Uma: fire, south, summer
Pachira should be called upon for matters relating to love and lust. For example, to make the one you desire fall for you. She is also an agent of retribution against those who commit crimes against love, or crimes of lust. Nothing angers her more greatly than to see someone taken advantage of to serve another's urges. Pachira represents a darker side of love, and therefore is at the peak of her powers during a spiteful waning moon.
Uma should only be called upon for cases where an afore-established love is being threatened. For example, to mend a suffering relationship, or to ease tension. Of course, one should keep in mind that Uma is only a third-rate magician herself. In the wrong phase of the moon, her meddlings could prove disastrous. Due to her nature, it is only recommended to invoke her powers during a waxing moon, as is the general rule for all workings of personal growth.
Liru is the jack of all trades; the services she renders may relate to love, wealth, health, or vanity. However she's a feisty one, and may rebel against the magician unless given a satisfactory tribute. But if appeased, she will serve faithfully. She is a werewolf, and therefore in her most potent state when the moon is full.
Aiko's primary services are those relating to knowledge. When successfully called upon, she may help the magician understand a specific topic, or just be more perspicacious in general. Of course, this doesn't mean you'll never have to study for a quiz again; she is only a guide. You'll have to do the bulk of the work yourself. A moon obscured in celestial darkness seems to have a strengthening effect on her robotic soul.
