It is in the style of Rurouni Kenshin's MANGA, not the film, not the cartoon, it is the original black-and-white MANGA.

No trigger words are specified, but the following cues will help:

monochrome, greyscale,

japanese_clothes,

retro_artstyle, 1990s_\(style\),

It is recommended to use 2D ckpt, e.g. Anything

weight about 0.9, and Hires Fix or i2i.

Also: I recommend the 4-part OVA anime Rurouni Kenshin: Trust & Betrayal to everyone.
