Can't remember the name of this anime

[Runic]

I was really young seeing this but I saw it in the early or mid 00s. I recal a blue haired female with a bow and arow skill. She's pissed because main guy with either black or brown hair because a random blond has begun living with him for whatever reason. I remember the main guy and blond girl woke in bed together early on after a night of drinking. As far as I can recal the animation quality was Ikki tousen ish but i could be wrong.

could be ecchi, i dont remember seeing any sex so i doubt its a hentai. I was like 10, maybe, when i saw this, that's why the details are poor.

I'll have to ask my anime friend about this one. He's pretty good at remembering animes and has seen a lot
