Description

くやし涙 Remaster 😢

悔しさや不満をこらえ、涙を浮かべながら歯を食いしばる「くやし涙」を表現する表情LoRAです。

2026年6月に公開した「くやし涙(Bitter Tears)」をベースに、教師データの構成から見直したリマスター版です。

無印版が持っていた、涙を浮かべる目元、強い頬の紅潮、眉間に力を込めた表情、歯を食いしばって感情をこらえる表現を受け継いでいます。悲しみそのものによる涙ではなく、悔しさ、不満、理不尽さ、負けたくない気持ちなど、納得できない感情を内側に押し込めている場面に適しています。

Remasterでは、無印版の公開後に得られた知見をもとに教師データを再構築しました。特に、女性の泣き顔や強い紅潮を中心とした教師構成がセンシティブ判定に影響する可能性を考慮し、男性を主体とした教師データへ大幅に再設計しています。これは表現内容を弱めるためではなく、元の「くやし涙」という表情を維持しながら、より安定して扱えるLoRAへ作り直すことを目的としたものです。

教師データは男性主体ですが、男性専用LoRAではありません。女性にも使用できます。 無印版と比較するとRemasterはやや自然でソフトな表情にも対応しやすく、LoRA強度や顔の大きさによって感情の強さを調整できます。顔を大きく映した構図では、涙、紅潮、眉間の力み、食いしばりといった特徴がより強く現れやすくなります。

無印「くやし涙」のコンセプトを継承した再設計版です。無印を単純に置き換えるものではなく、従来の強い表情表現を残しながら、教師構成と汎用性を見直したRemasterとして制作しています。


Bitter Tears Remaster 😢

A facial-expression LoRA for portraying bitter, frustrated tears while holding back emotion through clenched teeth.

This is a remastered version of the original “Bitter Tears” LoRA released in June 2026, rebuilt from the training dataset upward.

It retains the defining elements of the original: tearful eyes, strongly flushed cheeks, tense brows, clenched teeth, and the feeling of desperately holding frustration inside. Rather than ordinary sadness, it is designed for emotions such as frustration, dissatisfaction, resentment, unfairness, or the determination not to accept defeat.

For the Remaster, the training dataset was extensively redesigned based on observations made after the original release. In particular, the dataset now uses predominantly male training images to reduce potential sensitivity-classification issues associated with datasets heavily centered on flushed, tearful female faces. The goal is not to weaken the expression, but to preserve the original Bitter Tears concept in a more stable and versatile form.

Despite the male-dominant training set, this is not a male-only LoRA and works with female characters as well. Compared with the original, the Remaster can produce somewhat softer and more natural variations, while expression intensity can be adjusted through LoRA strength and framing. Close-up compositions tend to emphasize the tears, blush, brow tension, and clenched teeth more strongly.

This Remaster preserves the core concept of the original Bitter Tears while rebuilding its training structure for improved versatility and stability. It is intended as a redesigned companion to the original rather than a simple replacement.

tky_bitter_tears_remaster_frustrated_with_clenched_teeth_flushed_face_and_tears, In a full-body shot set in a Japanese-style room at night, a defeated young woman is hoisted into the air, her body limp and defenseless. A colossal, humanoid "Demon King"—standing three meters tall—grasps her head with one massive hand, leaving her dangling helplessly. Her right arm hangs loose with a semi-open hand, her left arm dangles just as limply down to the fingertips, and her legs hang slack. She features straight black horns, small fangs, fair skin, and long black hair in a "hime-cut" style; she wears a short red kimono with a yellow floral pattern—fully exposing her midriff and navel—and white tabi socks, with the kimono's hem parted to reveal her thighs. Her face, accented with red lipstick, bears yellow, upturned eyes that reflect her defeat, while her ample, slightly drooping bust reveals deep cleavage, her slender physique standing out against the dim tatami room. The space—a traditional wooden structure with shoji screens—is shrouded in shadow; low-angle lighting within this nocturnal scene evokes a tense, unsettling atmosphere, and the intricately detailed anime-style illustration radiates a palpable sense of violence and dread.,tky_bitter_tears_remaster_frustrated_with_clenched_teeth_flushed_face_and_tears

At night, in a castle within the Demon Realm, a woman has been defeated and subsequently crucified at the center of a sinister altar. Monsters jeer all around her; she is crucified, alone, bleeding from her forehead, coughing up blood, losing consciousness, and battered; her eyes are closed, tentacles are wrapped around the cross and tethered to her, and she hangs suspended with her arms outstretched. Monster 1: Orc (black); Monster 2: Goblin. Woman: (Tsundere, small fangs, large breasts, straight small black horns, black cape, black shirt, shirt with hem tied at the waist, short sleeves, short white gloves, red lace lingerie, visible cleavage, exposed midriff, black shorts, black fishnet thigh-high socks, short black boots, long white hair, side ponytail, red upturned eyes), photoreal, live-action style, natural skin texture, realistic shading, natural light, high-definition photograph, tky_bitter_tears_remaster_frustrated_with_clenched_teeth_flushed_face_and_tears
