Twelfth Green

Twelfth Green is a member of the Twelfth Five along with Yomotsu Hirasaka (Twelfth Red), Twelfth Blue, Twelfth Yellow and Twelfth Pink. He is arguably the best charcter in the series.

Personality
Not much is known about him. He's a very mysterious character.

The Cult of the Sixth
=== Four other people dressed like Twelfth Green join him on the roof of Omekata Temple, the green eyes coloured in blue, yellow, red and pink. Together, the quintet do a dramatic The Super Sentai inspired entrance, complete with an explosion set off by one of the Yomotsu impersonators. The five, identifying themselves as the "Quintwelve", leap down before Yuki, Yuno and Tsubaki and all introduce themselves as Twelfth. Talking one after the other, the five explain one of them has swallowed Minene's bomb which will explode shortly, and the real diary user ate the bomb. Yomotsu points out to Yuki the sins of the Omekata cult, planning to commit suicide by blowing himself and Tsubaki to pieces, revealing his diary has a Dead End flag. The Twelfth Five charge at Yuki, shuffling around to make it trickier for the trio to stop them. Yuno quickly realises Yomotsu is blind, picking up a rock and throws it at a rail. The sound of the rock causes Yomotsu to cock his head to listen to it, giving him away. Yuno races through the Quintwelve and slashes Yomotsu's throat with an axe. After that what happenned to the Twelfth Five is as much of a mystery as Twelfth Green himself. ===
