Shalnark Ryuseih

Appearing as an innocent and unassuming young man, this brilliant strategist serves as the intellectual backbone of the Phantom Troupe. As a skilled Hunter and the group's ninth member, he utilizes advanced technology and information gathering to support his comrades. His Nen abilities, Black Voice and Auto Mode, allow him to manipulate targets via antennas or temporarily boost his own physical power, though the latter leaves him vulnerable and amnesiac after use.
