Hazy Style

The Hazy Style (朧流), also known as the Hazy Lifestream Style (朧心命流), is a family of sword arts intermingled with aura centric techniques and designed to fight Spectres and Monsters.

This is the sword style used by most of the main characters in the series including Rimuru Tempest, Hakurou and Benimaru.

Background
The style–originally known only as the Hazy Lifestream–was created by Byakuya Araki around 400 years ago alongside his brother as a measure to counteract monsters and evil spirits. While in combat with said monsters, Byakuya and his entire platoon ended up being transported to another world, where they took refuge in a village of Ogres that took them in. As the Samurai and Ogres began to intermingle, their knowledge naturally began to spread to the entire village, with Byakuya personally instructing them all in the Hazy Lifestream Style which he renamed to the Hazy Style. His Grandson, in particular, was a natural talent who was able to properly inherit the inner mysteries of the Hazy Style and pass it on to future generations.

Back in Byakuya's homeworld, the Hazy Lifestream Style was carried on by Byakuya's brother, who founded a formal school in service to The Emperor. It remained pure and very close to the original style developed by Byakuya from generation to generation. Byakuya's brother's descendant, Gensei Araki, eventually became the head of the school and specially instructed 3 individuals of immense talent personally; those being Tatsuya Kondou, Masahiko Amari, and Saburo Minamoto.

Naming Variations
Commonly Haze・ (・) is added before the name of a technique, however Haze Black Flame・ (・) is added before Benimaru's version of Hundred Petals Rush and Imaginary Collapse Haze・ (・) is added before Rimuru and Ciel's Myriad Variety Petals. The reasons for the change in naming are not mentioned in the text.

 * Black Flame Slash (黒炎斬): Benimaru's take on the hazy style. The user coats their sword in Black Flame, delivering a devastating slash.
 * Plum Blossoms - Five Petals Thrust (──): One of the "mysteries" of the hazy style. The user pierces the opponent in five of ten vital points and uses the other five as feints. The vital points targetted are the eyes, throat, heart, kidneys, lungs, shoulders, and groin.

 * Hundred Petals Rush (百華繚乱): Carrera's take on the Hazy Style after taking Agera's experience as her own, and her greatest technique. The user delivers devastating strikes in the form of a hundred sword flash that transcend the speed of "Cherry Blossom - Eight Petals Flash".
 * Haze Black Flame・Hundred Petals Rush (・): Benimaru's take on Carrera's technique after seeing it in action. The user adds a superheated Black Flame to their sword using the power of Amaterasu and accelerates their body with its "Light and Heat Domination" to reach divine speed, delivering devastating strikes that cut and burn their enemy to nothing.
 * Myriad Variety Petals (千変万華): Rimuru and Ciel's take on the Hazy Style and one of their greatest techniques together. The sword's trajectory changes thousands upon thousands of times and slices through the enemy with elusive movements and impeccable power, pulverizing the target into dust and scattering it like a flower. The combination of the flexibility of a Slime and the toughness of a True Dragon enabled the two of them to achieve such an incomprehensible technique.
