"KAI" represents the preliminary stage where perfection is lacking, transforming into a new form. Under the title [RED], an entity emerges that fully demonstrates its ability to control the human mind. The happiness bestowed upon a person may exceed a certain threshold, making it impossible for them to maintain self-control, ultimately driving them into madness. Losing even basic judgment, the soul metamorphoses into a mere existence that can do nothing but accept. This is the "marionette" portrayed in this work. True domination manifesting in such a form is also, indeed, one of the truths.
