My main focus with this lora was the crossover characters featured in Sengoku Asuka ZERO's Danganronpa crossover event. However, there's enough general Sengoku Asuka ZERO material in the dataset to act as a nice overall style lora based on the setting. Essentially, it helps to push for a Sengoku period style similar to what modern fantasy is to the Western Middle Ages: a fanciful and stylized imagining of a historical era.

Danganronpa Character Costume Notes

The Danganronpa characters included in the crossover typically had two main images with Junko having an additional alternate. The main card image and an in-game sprite. The sprite is 'mostly' similar to the card but with an additional weapon. But they're still distinct with some having more major differences then others. You can make the sprite characters closeer to a standard anime style by removing the sprite, game_sprite,chibi, etc tags. These are the main costume tags for the Danganronpa crossover characters.

Use as a general style

If you use the asuka_zero tag it should act as a general style lora. In particular it'll pick up on things related to the Sengoku period like tags of: traditional_clothes, japanese_clothes, kimono, hair_ornament, ninja, samurai

You can also easily swap out the costumes from the Danaganronpa characters - for the most part. You can see some examples in the gallery using Tsumugi with Chiaki's outfit and a few more generalized examples.

Negative Tags

You'll probably want to use the following negative tags due to the problems noted in "Issues": border,card_(medium),card_game,collectible_card_game,divided_screen,frame,game_ui,hud,interface,japanese_text,text,mobile_game,ornate_frame,rating,sidebar,star_(symbol),symbol,yin_yang, GUI, orb, game_text,logo

Issues

I carefully hand captioned the danganronpa character imags from the dataset to ensure all GUI/card/text elements were accounted for. What I didn't account for is that a lot of the danbooru images didn't have the game elements captioned. Users there are typically pretty good about it and this led me to being overly lazy about double checking. The end result is that the GUI elements from the cards like star ratings or card borders have a chance of showing up ingenerated images even when using negative tags to try avoiding them. If I do updated versions of this lora I'll fix that.
