Yamate

One of BLOCK's operatives, Yamate (山手) was within the task force in charge of cleaning SCHOOL's trail. They choose to indirectly support SCHOOL's operation as the extra distraction provided suited BLOCK's main objective. Etzali was in their targeted place when Yamate's party decided to ride it.

In order to escape unarmed Etzali decided to attack one of his enemies and take his appearance using his magic, Yamate was on the unlucky end of that strategy. What Etzali didn't know was that Yamate was one of BLOCK's main members, and as such he couldn't simply slide away unnoticed and was forced to keep himself undercover indirectly monitoring BLOCK's current activities.

BLOCK's member never realized that Yamate was replaced, even after Etzali escaped the group. , though GROUP noticed immediatly Etzali's strategy once Tsuchimikado Motoharu saw the real Yamate's injured body

Trivia
Etzali thought to himself that it was strange that Yamate was someone important for his organization, despise him being pretty weak.
