Sage Art: Radiating Ink Truth-Seeking Rasenshuriken

Combining Senjutsu chakra, Yin Release, and Yang Release with ink, Keiku forms a Rasenshuriken. Once thrown, after it travels the desired distance, the user detonates it, causing it to rapidly expand in size while releasing dark light. This light is enhanced with a unique sealing ink that covers everything the light encounters. Upon saying "Seal", the ink seals away half of whatever it touches, reducing its speed, endurance, durability, strength, exc., by half. Keiku seems to be excluded from the sealing dark light ink properties, as when it touches him, it disappears instantly. After the technique ends, the Truth-Seeking Ball returns to Keiku. This 'dark' or inverted light is able to penetrate the defenses of Susanoo due to its properties, though it can't penetrate the defenses provided by Reiyuigon or Reihogosha.
