About 90 years ago, there was a famous swordsman who battled Miyamoto Musashi in Ganryujima… this is the 4th generation from that line of swordsmen.

She has undertaken gruelling training to take her fencing techniques to the next level and kill Miyamoto Musashi. She certainly spilled some blood to get her new power, but fueled by her fixation on putting an end to Musashi's life, Kojirou didn’t think much of the arduous training regime.

After some digging around she found the perfect dress for slaying Musashi and swears this is her lucky dress. She also found her precious blade the "Bizen Nagamitsu" in storage! This weapon has been endowed with a soul of its own and has become self-aware. This is the beloved blade of the first generation Kojiro, it has exchanged blows with Musashi’s "Yamoto no Kuni no Kunimune", and has had some unparalleled encounters with the blade.

Nagamitsu is capable of speaking and can be heard nagging at Kojiro. In turn Kojiro just continues on with what looks like mindless soliloquy. Kojiro pays no mind to what others think of her.
