=== The Survival Game Saga ===
Takao Hiyama was a killer at least two years prior to the events of 
the Survival Game. He appears in the first episode, warning the students
 in his class, which include Yuno and Yukiteru, to be aware of the 
serial killer, even though he was the serial killer himself, evidenced 
by the fact that he the same night stalked a woman and later murdered 
her.
Muru Muru appeared and presented him his Future Diary, however as
 paranoid as Hiyama was shown to be, it did in fact take three attempts 
for him to realize it recorded his future and that Muru Muru was not 
recording the crime he committed.
The following day Hiyama went to realize that Yukiteru also was a
 Diary owner himself after he was taken in acing his math test using the
 results shown on his Future Diary. Hiyama also encountered another 
Diary owner at the old art university the same day, 9th, Minene Uryu, however Minene fled from him to join forces with Masumi Nishijima to escape him.
Later Hiyama is shown to target Yukiteru and follows him to a building, 
unaware that Yuno, the 2nd Diary owner, in fact was helping Yukiteru and
 averting his death. As Hiyama reaches the roof, he is unable to find 
both Yukiteru and Yuno, and he quickly pulls out his diary to locate his
 targets. At this point Yuno runs out to distract Hiyama, and as 
Yukiteru leaps up from his hiding place, he tosses one of his throwing 
darts and shatters Hiyama's diary. Hiyama is quickly erased from 
existence, much to the surprise of Yukiteru , and it happens at this 
points that the other diary owners concludes Yukiteru to the most 
dangerous diary owner, prompting most of them to target him.
