>>78994510>Assuming you're talking about Niji suing Kamame for working on Doki's new skinsuit, and not Doki for commissioning her new skinsuit:For copyright infringement? Absolutely not. Doki has a Legally Distinct Hairclip™ and a pair of Legally Distinct Hair-Wings™; and any other visual similarities between Dokibird and Selen Tatsuki are coincidental and unintentional (Wink!).
Niji would have as much casus belli against Kamame on that front as Cover would for them giving Doki blonde hair and green eyes.
For slander/defamation/reputational damage/infringement of honor?
....maybe, considering how Japanese law on that matter works, and Niji's world-famous animosity towards Doki in particular. Whether Niji would win such a lawsuit against Kamame is a discussion for a different thread, but that has no bearing on whether or not they could or would file such a lawsuit in the first place.
>Niji cannot sue Doki at all, lest they open themselves to discovery in a Canadian court
