Flonne College Cutie — H3

Creator: CitronLegacy

FlonneCollegeCutie_H3 preview

Dataset Description

A small, hand-captioned LoRA training set for the character Flonne (Disgaea) in a "college cutie" school-uniform look. It has two parts: still images and short voice/audio clips, each paired with a sidecar .txt caption.

Intended for:

  • Character / style LoRA training (image and audio-video models)
  • Captioning-format experiments
  • Small-dataset fine-tuning tests

Dataset Structure

The dataset is uploaded as a single zip (FlonneCollegeCutie_H3.zip) containing one flat folder of 76 files (~2.6 MB) — 38 media files and 38 matching caption files, no subfolders.

Part Files Naming Notes
Images 13 .jpg FlonneCollegeCutie_IXL_<001–013>.jpg Portrait crops: 464×688, 289×437, 277×416, and 216×216 (non-uniform)
Audio 25 .mp3 v12_clip_<start>-<end>.mp3 1.2–4.5 s each, ~68.5 s total
Captions 38 .txt same basename as the media file One caption per file

Audio clip names (v12_clip_8-9) come from the start–end second marks of the source cut. Clip 33-34 and 33-35 overlap.

Caption format

Every caption starts with the trigger word, then natural-language text. Trigger word: fl0nn3C.

Image caption:

fl0nn3C, fl0nn3C adorned with a large blue bow on top stands facing forward, wearing a school uniform that consists of a pale yellow blazer with a matching blue bowtie at the collar, a blue and white plaid pleated skirt, and long sleeves, ... set against a plain dark background in a full-body shot. static image, no motion

Audio caption (dialogue is quoted, ambient sound is described):

fl0nn3C, She says, "What do you call those guys in the human world?", jazz music in background

Data Collection

All images are original fan art created by CitronLegacy and captioned by hand and with AI assistance. Images were chosen to cover a consistent outfit (school uniform with blue bow) from several angles. The audio clips are official Disgaea content, not created by CitronLegacy, and are short single-line voice snippets.

Intended Uses

  • Training a Flonne character LoRA
  • Testing audio+text conditioning in small-scale fine-tunes
  • Non-commercial research and education

Limitations

  • Very small (13 images, 25 clips) — suited to LoRA training, not general model training.
  • Image resolution is low and not uniform; resize/bucket as needed.
  • Audio is speech over background music, not isolated voice.
  • Captions are not guaranteed accurate; a few use "her/she" with no named subject.
  • Single character, single outfit.

Licensing

Important

The images are original fan art by CitronLegacy. The audio clips are official content that is NOT owned or created by CitronLegacy. The character Flonne and the Disgaea franchise are NOT owned by CitronLegacy; they are the intellectual property of Nippon Ichi Software.
