Summary
Itsuki serves as Sensui’s right-hand man, assisting in the execution of his malevolent schemes. Although he possesses formidable psychic powers, he requires an ability capable of tearing through dimensions to fully realize his master's goals. This necessity brings Kuwabara into the equation, as he is the only individual in Ningenki capable of such feats. The bond between Sensui and Itsuki originated from a chance encounter where Itsuki, acting as a youkai, attempted to defeat Sensui in battle but failed. Spared from death because he was a demon target of Sensui’s, Itsuki was granted a single wish before his execution. He asked for just one more day to watch the final episode of his favorite television series, which coincidentally was also Sensui’s favorite. This shared interest forged a close companionship between the two. Throughout the narrative, Itsuki’s intense interest in Sensui is evident through his constant observation of his master. He meticulously monitors Sensui’s every move, analyzing his emotions, weaknesses, and combat skills with unwavering attention.
