赤冬 Akafuyu（明日方舟）· MOSS-Image 角色 LoRA 明日方舟「赤冬」的角色 LoRA。紫发带红挑染、长发、橙色眼、唇下小痣，覆盖本体（精零 原皮）、本体（精二 原皮）、皮肤 心性。在 MOSS-Image Base 上训练，建议使用 SFT 模型跑图。 已知问题：服装还原度还差一点：原皮的头饰完全不像。尚不确定是素材质量不足还是每套服饰的重复次数不够，将在后续训练里核实。 已知问题：素材与核对表里带了「脸上的痣」这种小而散的特征，导致部分生成图会出现很多颗痣（提示词已改为 tiny mole under mouth 收敛）。 【角色触发词】 MoChaAkafuyu把触发词放在正向提示词第一行，逐字一致，前后不要加空格或标点，后面换行写画面。 只写触发词就能出角色特征（紫发带红挑染、长发、橙色眼、唇下小痣），但不指定服装；没写服饰时服装会随机，这是角色 LoRA 的正常表现。 【本体（精零 原皮）】 MoChaAkafuyu, 1girl, purple hair, red streaks, long hair, orange eyes, tiny mole under mouth, black shirt, black coat, long coat, arm armor, red pants, black belt, multiple belts, buckles, red sash, ribbon, red ribbons, hair ornament, black sandals, sandals, red straps, katana, sword, scabbard, sheath, sword over shoulder【本体（精二 原皮）】 MoChaAkafuyu, 1girl, purple hair, red streaks, long hair, orange eyes, tiny mole under mouth, black shirt, black coat, long coat, arm armor, red pants, black belt, multiple belts, buckles, red sash, ribbon, red ribbons, hair ornament, black sandals, sandals, red straps, katana, sword, scabbard, sheath【皮肤 心性】 MoChaAkafuyu, 1girl, purple hair, red streaks, long hair, orange eyes, tiny mole under mouth, glasses, black peaked cap, hat, black jacket, white collar, white cuffs, white shirt collar, necktie, gloves, dark teal skirt, skirt, black high heel boots, ankle boots, ring, jewelry, book【换装】 保留触发词，衣服写细一点；不想要官方服饰就把它放进负面： 负面： 【推荐参数】

Akafuyu 赤冬 (Arknights) · MOSS-Image Character LoRA A character LoRA for Akafuyu from Arknights. Purple hair with red streaks, long hair, orange eyes, tiny mole under mouth; covers Base outfit (Elite 0), Base outfit (Elite 2), Temperament skin. Trained on MOSS-Image Base; running it on the SFT model is recommended. Known issue: Outfit fidelity is still imperfect: the base-form headpiece does not resemble the official one. Not yet clear whether the material quality or the per-outfit repeats are the cause; to be verified in a later training run. Known issue: The reference sheet carried a small facial feature (a mole), so some generations scatter many moles across the face; the prompt now uses 'tiny mole under mouth' to tone it down. 【Character trigger】 MoChaAkafuyuPut it on the first line of the positive prompt, exactly as written — no extra spaces or punctuation — then a newline and your scene. The trigger alone already produces the character's features (purple hair with red streaks, long hair, orange eyes, tiny mole under mouth), but it does not specify the outfit — with no outfit tags the clothing is random, which is normal for a character LoRA. 【Base outfit (Elite 0)】 MoChaAkafuyu, 1girl, purple hair, red streaks, long hair, orange eyes, tiny mole under mouth, black shirt, black coat, long coat, arm armor, red pants, black belt, multiple belts, buckles, red sash, ribbon, red ribbons, hair ornament, black sandals, sandals, red straps, katana, sword, scabbard, sheath, sword over shoulder【Base outfit (Elite 2)】 MoChaAkafuyu, 1girl, purple hair, red streaks, long hair, orange eyes, tiny mole under mouth, black shirt, black coat, long coat, arm armor, red pants, black belt, multiple belts, buckles, red sash, ribbon, red ribbons, hair ornament, black sandals, sandals, red straps, katana, sword, scabbard, sheath【Temperament skin】 MoChaAkafuyu, 1girl, purple hair, red streaks, long hair, orange eyes, tiny mole under mouth, glasses, black peaked cap, hat, black jacket, white collar, white cuffs, white shirt collar, necktie, gloves, dark teal skirt, skirt, black high heel boots, ankle boots, ring, jewelry, book【Outfit swap】 Keep the trigger and describe the clothes in more detail; if you don't want the official outfit, put it in the negative: Negative: 【Recommended settings】
