Chara-Kami is the deity who inflicted the "Absolute Choice" curse upon Kanade Amakusa. This flippant god communicates exclusively through phone calls, delivering missions or intervening in Kanade's predicament, and is saved in Kanade's contacts as "Flippant God" due to an apparent lack of seriousness and a penchant for trolling. The god's motivations remain ambiguous, hovering between deriving amusement from Kanade's suffering and offering a potential path to lift the curse.

Originating from the higher plane called the "God World," which dispatches agents like Chocolat to assist Kanade, this deity directly assigns Kanade a series of missions. Completion promises curse removal, but failure guarantees eternal suffering. These missions invariably involve interactions with female classmates, with the god implying that "falling in love" is the ultimate objective to break the curse, though specifics are withheld.

The god enforces compliance with the curse by inflicting debilitating migraines should Kanade resist or hesitate in making a choice. Demonstrating reality-warping power, the deity once transformed Kanade into a girl as tangible proof of divinity, presenting it as a test with permanent gender alteration as a possible consequence. These actions reveal a capricious nature blending cruelty with absurdity.

An implied, undefined connection exists between Chara-Kami and Seira Kokubyakuin, the student council president who possesses knowledge of the God World and the curse's mechanics. Seira withholds this information, mirroring the god's tendency toward obfuscation. The god's role remains consistently that of the orchestrator of Kanade's trials, leveraging the curse to disrupt his life while offering narrowly defined avenues for redemption.
