Traveling and binding
The protagonist travels to the world of Conan and is bound to the [Literary Vest System]. Points unlock the function. You are lacking in mental energy at the beginning and can only use one vest at a time. As the plot progresses, mental power gradually grows, unlocking more vests and linkage abilities.
Six vests
Dazai Osamu, Edogawa Ranpo, Sakaguchi Ango, Mori Ogai, Akutagawa Ryunosuke, Fyodor Dostoevsky. Each literary hero's appearance, personality, and abilities are 100% restored to the original version, and each has its own unique skill tree and growth path.
Soul origin
All vests have the same soul and can chat privately, fight each other, and collude in real-time. Memory and cognition are retained when switching vests, forming a unique "one person, six sides" narrative tension.
Concept: A soul from another world wakes up in Miwa Town, and the gears of fate begin to turn.
