Calibur Meister

Izumo is a girl who fights magical "artifacts" and their evil wielders with her own magical sword. However, she's really socially awkward and has a hard time talking to people. Mostly she just finds herself able to speak with tools and the souls of magical tools, including the cheerful and extremely extroverted human form of her sword's soul. Will she be able to learn that there are some people worth making the effort to talk with?
