Pukin Fanbook 1 Entry

固有アイテムである細剣で対象を傷つけると、その認識を変化させられる。
敵と味方を勘違いさせたり、感覚の一部を失わせたり、幻覚を見せたりと、自由度は非常に高い。
また、未知の言語を習得させたり、特定の能力を高めたりといったことも可能。
この魔法を行使できる対象は同時に一体のみ。
新しい対象に魔法をかけた場合、その前に魔法を使っていた対象の認識は元に戻る。

If a target is damaged by Pukin's unique item, her rapier, she can alter a target's perception.
Pukin can alter plenty of things about the target, like mistaking enemies for allies, making them lose parts of their senses, or even showing them hallucinations.
Pukin can even make her target learn languages they did not previously know, or grant them abilities they did not previously learn. She can even improve their abilities.
She can only use this on one target at a time.
If Pukin uses her magic on another target, the magic on the previous target will be cancelled.
