No.3

No.3 (三番目(達)) is the third and final Heartseed-like being encountered by the Cultural Research Club. No.3 appears in Asu Random I and drags much of Yamaboshi High's student body into an Isolation Dimension. Like No.2, No.3 acts independently from the original Heartseed, who is opposed to No.3.

Personality
Like the original Heartseed, No.3 speaks and acts in a slow, lifeless manner, as if bored. Even more so than Heartseed and arguably No.2, No.3 is quite malicious, having no qualms about tormenting the innocent students of Yamaboshi High with phenomenons. Unlike Heartseed, No.3 fully accepts Record Deletion, wishing to impose it on the StuCS and Heartseed.

Motive
No.3 motive for sending every student in first and second year to the Isolation Dimension was for experimentation to see how each group would respond to the phenomenons. Because he didn't want the StuCS to interfere with the Isolation Dimension, he told the rest of the students that the StuCS is ther reason they are in the Isolation Dimension. This made the other students afraid of the member of the StuCS and lost their trust in them.

Appearance
No.3 does not appear in person, instead choosing to possess a 1st year student to converse with others. While possessing someone, the possessed person adopts a lifeless disposition akin to other possessions.

Phenomenons
No.3, as with all Heartseeds, is powerful supernatural entity and was able to pull a large number of individuals into an "Isolation Dimension" of No.3's own design where they may be freely toyed with without outside interference. No.3 has displayed the power to invoke numerous phenomenons at once while in the Isolation Dimension, allowing him to affect several groups at the same time, each group suffering a different phenomenon.

Authority
Holding an even higher authority than Heartseed himself, it is implied that No.3 may be the leader, or at least an authoritative figure, amongst the Heartseeds. In addition, it is heavily implied that No.3 is not a single being like No.2 or the original Heartseed, but perhaps a group of beings collectively known as No.3. This made the StuCS fear that No.3 could be watching them from anywhere, at any time, which made them more cautious of their actions in the beginning. No. 3 did not appear to be aware of No.1 entering the Isolation Dimension.
