New Dominion Tank Police is a follow-up to the first OVA series which takes place in the world of the first manga (so not based on Dominion Conflict). It takes place in a sort of shared universe of Masamune's other works. i.e. Dai Nihon Giken from Apple Seed and Ghost in the Shell is heavily featured. The Fuchikoma feature, as well.
Characters available are:
Leona Ozaki (レオナ尾崎)
Annapuna and Unipuma (アンナプーナ/ユニプーマ)
Sophie Udagawa (ソフィー宇田川)
Mayor Weatherby (ウェザビー市長). If using WAI, specify cheekbones in the prompt, explicitly. Otherwise, she looks way cuter than she should...
For Leona, without specifying the clothes in the samples, it tends to try and generate one of the twins. You can remedy this by using "leonatankpolice, brown hair, short hair"
