Anime Looking for a series! What's the name?

[Dinosaurcerer]

I only saw one youtube clip.

Male MC walks into a room, there is a girl within who seems to be obligated to have a swordfight with him. She does so halfheartedly and throws the sword at him, he deflects it back and knocks her out and he leaves nonplussed.

I want to say one of the characters had a blue color scheme and the other red or brown

Devil May Cry maybe? Can't say your description is much to go on.

 

[Konatalzumi]

Sounds like a yakuza qte

 

[SpcDaicon]

Chivalry of a Failed Knight, maybe?

 

[Antilocal123]

Fortnite!
