About

1. Biological Characteristics of Yukkuri Structure: Single-segmented (manju-shaped), they breathe, eat, and excrete (anko/bean paste). They lack bones or complex organs; their insides are filled with sweet bean paste. Fragility: Extremely fragile. The skin tears and paste leaks with slight impact or environmental changes. However, they possess high vitality and resilience, surviving even after losing most of their body. Nutrition: They generally prefer sweet things. Reproduction: They are hermaphroditic, producing "Red Yukkuri" (babies) using "sperm paste" and "womb paste." A stalk grows from the mother's forehead, and the babies grow from it like fruit. Weakness: Vulnerable to water; they dissolve when submerged (and show intense fear before dissolving). 2. Personality and Intelligence Personality: As their catchphrase "Take it easy!" suggests, they prefer peace but are extremely self-centered. They treat humans who dote on them like "slaves" and maintain an arrogant attitude (demanding others to "Take it easy!"). Intelligence: Extremely low. They have almost no learning ability and will repeat the same mistakes even after being abused. Arrogance: They cannot understand human property rights and will shamelessly demand things belonging to others. If denied, they fly into a rage, screaming that they "can't take it easy." 3. Types and Variations in Yukkuri Abuse (Yu-gyaku) In abuse-themed works, variations based on original characters (Reimu, Marisa, etc.) appear with specific traits. Gesu (Scum) Yukkuri: Arrogant, selfish, and looks down on humans. The most typical target for abuse. Stray Yukkuri: Living in harsh environments, they often turn into Scum types. Pet Yukkuri: Kept by humans, but can become Scum types if poorly raised. Pure/Young Yukkuri: Not yet corrupted, pure and helpless. Abuse of these types is often framed as particularly disturbing (munakuso-kei). Derived Species: Unique appearances like Kimeramaru (plush-like bodies) or Macchori (muscular types).
