Chizakura Sappo

Chizakura Sappo (血桜殺法; Blood Cherry Killing Method) is a collection of life-taking techniques taught in the Oboro School to ninja of Mikazuki rank or higher. The user of the techniques use skills and techniques ranging from stealth, to masking one's presence and at times combined with high speed movements to get into a target's blindside or in extreme cases take down hordes of opposition with total ease. The skill is made up of two types; Hyogi, which focus on Taijutsu attacks that range from out in the open attacks, and Rigi, which focuses on stealth kills and high speed elimination without giving foes time to scream. It is said that masters can eliminate targets and threats with sound alone.

表技Hyogi

 * 「殺陣」 Lethal Gale- One of the most well-known and lethal of Chizakura Sappo. The skill was inspired from the concept used in Edo Kabuki battle plays. Masters of this skill move with such speed into an opponent's blind spot that the human eye can't catch up, and are struck down with such deadly precision that by the performer of the technique sheaths their blade the defeated drop in pools of their own blood.
 * 「金剛落し」 Falling Vajra- An aerial assault in which the user comes down with a high speed somersault slash from top to bottom rending those struck in two.
 * 「昇銀流」 Rising Silver Flow- A powerful upward slash that can rend the target in half or at the very least cause a serious wound to the upper body.
 * 「大裂斬」 Great Rending Slash- a defensive counterattack in which the assault of an opponent is repelled and followed up with a high-speed and powerful slash attack that either sends the enemy flying or splits them in half
 * 「暮鶚落し」 Twilight Osprey Drop- A high speed assault in which the user gets into the target's blind spot and knocks them into the air then jumps after them, bringing them higher up with a sudden grab from behind, and bring their opponent coming crashing down with great speed and force onto their skull. At higher altitudes this technique can even split the skull open, or for tougher opponents cause serious damage.
 * 『武鷲落し』 Descending Martial Eagle- A skill inspired by the Iga Hattori clan, this skill causes the ninja to knock a target into the air like with the Osprey Drop. But instead of bring them down to earth crashing, the ninja throws them down with great force using their legs and a aerial backflip, sending the hapless target careening head first to the ground.

裏技 Rigi

 * 黄泉霧 Underworld Mist- using an electromagnetic smoke bomb to fry enemy machine operations, the user uses the smoke to conceal their movements and eliminate all foes caught in the smoke.
 * 乱月 Chaotic Moon- a lethal and difficult Oboro Style technique, the user erases their presence and completely mask their Ki (気;vital force), and at lightning speed slash through opposing forces without stopping until the final strike is dealt and the blade is sheathed (regardless of whether it is a sword or dagger).
 * 夜桜 Night Blossom- Using shuriken from the shadows, the ninja unleashes a fearsome barrage of kunai or bo-shuriken targeting the vital points of his targets. It is a Master Rank and more lethal form of Hasso Shuriken.
 * 紫電　Shiden- A consecutive stealth kill technique that allows the target to obliterate an entire room of enemies unnoticed.
 * 冥途刃鎖 Netherworld Blade Chain- using chains with blades, the ninja uses the technique to draw and quarter a target. The sight of the eviscerated corpses are known to overwhelm the surviving targets with terror.
