Nitoryu Seiken

" The sword is not a means to justify the actions of it's user, it's to determine if the user has enough resolve to stand by what they believe. Splitting mountains, destroying the earth, and even slicing the sky! There is nothing the Twin Sword Style cannot cut! "Nitoryu Seiken (ツインインフィニティ Lightning Infinity)is a unique sword style that has been passed down to the main house of the Mikigami Clan. The style is known for its incredibly powerful and precise swordsmanship that is born out of the user's resolve to manefist his killing intent. The only known users of this unique style of swordsmanship are Fuko (the current clan head) and his son Hibiki. Hibiki is next in line to inherit leadership of the clan after his father due to his sister abruptly leaving the village and betraying the clan by stealing Ryuuenza.

One is said to have trained for almost two decades to completely master this sword style, but Hibiki was able to master the fundamentals of it within only a few years, completely breaking the record set by his own father.

History
As far as history goes, this secret sword style has been taught to the next head of the family and he or she would have to take over the school to teach the next generation, repeating the cycle. The secret sword style was a means of teaching young and able swordsman the ways of surpassing human limitations and forging their names in history as legendary warriors. The common use for the style was for bounty hunting and slaying mythical creatures (though these just tend to be rumors to excite the young children and get them anxious to learn it). It is unknown when the style was originally invented but Hibiki’s father, Fuko stated that the style has been passed down only once meaning that the style is most likely a few decades old.

Within the Mikigami clan, there are two separate houses and only the ones from the main house are allowed to learn the forbidden techniques of the style. The lower branch family has been given permission to learn the more basic moves but nothing more. The advanced techniques are reserved for only high ranking family members who are in direct line to be in the clan.

It is revealed that the Mikigami Clan are rivals with the Kosaka Clan and have been since long ago. Though, this rivalry is strictly friendly and the members are not at war or anything that menacing, it’s just the original founders of both clans are actually brothers but they both walked different paths and while one created this style, the other stuck with the Kosaka Blade style. This made things even more frustrating between Hibiki and Alidia because they both come from their own respective clans and are constantly engaging one another in friendly duels to see which clan can triumph.
