Orin Miyashiro

Orin Miyashiro (宮代 お鈴, Miyashiro Orin) is an assistant to the Eighth Diary Holder, Kamado Ueshita. She owns the Apprentice Diary, "The Orphan Diary".

Plot
Orin Miyashiro is an orphan who lives in the Mother's Village orphanage run by Kamado Ueshita. She assists Kamado in running the orphanage.

When the Survival Game commenced, Orin infiltrated the Omekata Temple along with one half of the Seventh, Ai Mikami, to gather information about the other diary holders.

After Kamado made an alliance with Yukiteru Amano and Yuno Gasai, Orin, Ta-kun and around twenty other orphans ambush the Eleventh John Balks on a mountain road. However, John Balks disables their apprentice diaries with a signal jammer in his car, and thus removing any advantage that Orin and the orphans had. At this moment, Orin tells Yuno to destroy the jammer, only for Yukiteru to betray their alliance, backstabbing the orphans by shooting them with a pistol. Yuno in turn unsheathes her sword and attacks Orin, killing her.

Third World
In the anime, Orin and Ta-kun, both with expressions of displeasure, stand in front of the orphanage to see off Kamado, who walks away arm-in-arm with John Balks.
