Jinnai Shinobu

Perfect Shinobu

I can get along with any Youkai.
~ Jinnai Shinobu
I don’t know why, but Youkai and similar things have always really liked me. To be honest, I really don’t think you’re going to eat me here. But that’s the point. This isn’t about form, power, or attributes. What moves your heart and fills you with strength comes from somewhere else.
~ Jinnai Shinobu to Fenrir

Notable Attacks/Techniques:

  • Unique Trait/Ability: Shinobu has the strange trait of attracting the supernatural and supernatural beings, being able to approach and befriend any kind of Youkai, even extremely dangerous ones. It has been noted by Yukari that Shinobu is completely unaware of the forbidden line that everyone else can naturally sense. For example, as a child, despite finding places such as a school at night, an abandoned hospital, or a sealed-off tunnel scary, he would never think of turning back. This trait not only makes Shinobu immune to the fear Youkai and the supernatural normally cause on people, he's also immune to techniques that try to use fear against him. Saiki Kazu's killing intent technique, which can paralyze, cause difficulty breathing and almost knock out experienced specialists such as Hishigami Mai and Illness Magic User, completely failed to affect Shinobu. Not only that, Shinobu's nearby allies were also capable of acting normally thanks to their bond with Shinobu. Kazu described Shinobu's ability as "the ability to neutralize the fear and create a bond, giving him a great affinity with any Youkai", similar to Ranzono Sachi’s affinity with animal Youkai and her ability to summon them, but more indiscriminate and covering a wider range. According to Kazu, if Shinobu were to be able to wield it consciously, he would individually have been able to recreate the phenomenon known as Hyakki Yakou (A hundred different species of Youkai marching as one). This was proven when child Shinobu first considered someone an enemy after they hurt Yukari in front of him. His cries of despair gathered the attention of thousands of his Youkai friends, turning them into a living avalanche and a frenzied mob that chased down and tore the offender apart.
Shinobu Robot

Robot's design and size comparison to a human

  • Robot: An eight-legged crab-like weapon created by Shinobu, capable of easily destroying a wall. The robot can also act as a receptacle for a demon, increasing its power exponentially and becoming able to easily kill Hishigami Mai, who had initially deemed the robot "a piece of junk" incapable of killing her.
  • Summoning: Together with his scientific knowledge, in the alternate future Shinobu became an experienced magic user, being able to not only summon the Succubus to his side but also able to summon and control Tselika, one of the strongest demons in the world and comparable to the demons symbolizing the Seven Deadly Sins.
