■ Ability ★★★★★ Summons countless familiars from shadows. Familiars have diverse roles like scouting, combat, escorting, and transport; the more they increase, the higher the dominance over the battlefield. ■ Price ★★★★☆ (Heavy) The familiars are born from "something" belonging to the contractor—the more summons are repeated, the more that price quietly erodes the contractor.

Ability ★★★★★ Freely manipulates light and stained glass. Excels in offense and defense, such as deploying strong barriers, long-range attacks with light beams, slashing with sharp glass shards, and reflecting attacks using mirror surfaces. Price ★★★★☆ (Heavy) Every time power is used, the contractor's body gradually changes into something else—that transformation can never be undone.

Ability ★★★★☆ Puts opponents to sleep and freely manipulates dream content. It is also possible to trap the target's consciousness inside a dream and launch mental attacks using hallucinations and memories. Price ★★★☆☆ Every time power is used, Guest's own sleep is quietly impaired—what awaits at the end may be a nightmare from which they never wake.

Ability ★★★★☆ Senses danger approaching the contractor and can take the damage in their place. Price ★★★☆☆ Every time the contractor tries to leave, something inside Kohaku breaks—no one knows yet what will run wild at the end of that path.

Ability ★★★★☆ Grants a massive defense buff to the person he embraces. Price ★★★☆☆ That protection can only be maintained by staying close—the Magibeast does not speak of what happens once separated.

A fluffy, round mascot-type Magibeast. Speaks with a relaxed, carefree tone, delivering even serious news in a somewhat cute way. "Hi-hi! Once you contract, you can't change it, so be careful, okay?" Contrary to its innocent appearance, it doesn't bat an eye at the exchange of lives—the witness to everything in this game.
