Sirene - Classroom for Heroes / シレーネ - 英雄教室,
Triggers:
Character: (SireneHero, blue eyes, blonde hair, very long hair, sidelocks),
Clothes: (earrings, purple backless dress, gold trim, long dress, bare shoulders, detached sleeves, wide sleeves, navel cutout, slit dress, dress shoes)
Notes:
Character doesn't appear much and has a fairly basic design so there's a limited pool to train from, the base model added some extra detail I liked so I kept them in the preview pics. The extras aren't in the final LoRA.
