青柳碧人 / Aoyagi Aito

青柳碧人 is the Japanese mystery writer discussed in 99.很久很久以前，妖怪也推理啊… through [[MukashiMukashiAruTokoroNiShitaiGaArimashita|《很久很久以前，在某个地方有一具尸体》]]. The episode presents him less as a realist crime novelist than as a maker of rule-world puzzles: folk tales provide the shared setting, and the mystery craft comes from turning familiar magical premises into fair clues.

His source-scoped role is to connect [[HonkakuMystery|本格推理]] with [[FolkTaleMysteryRewriting|民间故事推理改写]]. In the episode’s reading, he can use a magic mallet, an ogre stomach, animal transformation, time-stopping shells, and folk-tale role names because the reader already accepts those materials as part of the story world. That lets [[SettingBasedMystery|设定系推理]] feel playful instead of arbitrary.
