I was told some time ago by a client about a very peculiar weapon the would grant one the ability to use their chakra nature as though it were the blade itself. As such allowing one to quite literally coat the blade of the weapon in their chakra and have either a lightning or fire blade. Well that's how I imagine it works anyway, I suspect water, wind, and earth are also possible and likely add different effects to the blade.
However I also learned a disturbing fact about the blade. It possessed a curse that inadvertently corrupted the heart of the wielder causing them to bring harm to comrades or worse, the general populace. Not only that, but that a crime lord near the coast of Makai no Kuni was also currently in possession of the blade and reaping havoc across the coast. While the blade interests me I have made a decision to act my part as Captain of the police force of our country and handle this situation. I dare not bring any comrades with me for I fear that once I attain the blade it may corrupt me too before I can seal it away once and for all.
Tonight I will venture to the coast of Makai no Kuni to a local port town where I will then locate this crime lord and put an end to him. I do not know how strong he is nor whether or not he had an army of henchmen at his disposal, but I have confidence that I'll complete the task set out before me without complication.
