Yoshikishi

Yoshikishi is theatrical and energetic, matching the exaggerated visual-kei presentation of HAYASii. His individual personality receives relatively little focus because the band generally operates as a unit.

He approaches supernatural exorcism with the same intensity as a stage performance. There is no indication that he finds the bizarre circumstances surrounding Seiko's requests unusual; performing amid occult activity is simply part of the band's work.

His commitment to the performance is important because HAYASii's effectiveness depends on producing sustained, forceful music while an exorcism is underway.

Yoshikishi has no independently established supernatural technique. His principal skill is drumming, which contributes to HAYASii's musical exorcism.

The band's music is used as part of a spiritual ritual designed to drive supernatural entities from a possessed host. Yoshikishi provides the percussion that supports the performance while Seiko manages the occult components of the procedure.

His ability therefore functions collectively rather than as a personal power. HAYASii's effectiveness comes from the full band's performance combined with the knowledge of the spiritual practitioners directing them.

Yoshikishi appears when Seiko calls HAYASii to assist with Jashi, the Evil Eye possessing Jiji. The proposed solution is an exorcism using the band's intense music to force the spirit out.

The resulting performance transforms the Ayase residence into the equivalent of a visual-kei concert. Yoshikishi drums alongside the rest of HAYASii as the ritual begins and Jiji's possession reacts violently.

The attempt demonstrates how broadly Seiko interprets spiritual practice. Traditional ritual, modern music, psychic power, and brute force all coexist in her methods, with HAYASii serving as a recurring specialist resource rather than an ordinary entertainment band.
