13th Hunter Chairman Election arcEdit
Teradein ends up with the 7th place in the fourth round of the 13th Hunter Chairman Election, thus qualifying for the fifth round alongside 15 other candidates. He desires to radically overhaul the Hunter Examination.
Killua Zoldyck warns Morel McCarnathy that his older brother is going to attack he and Alluka with brain-washed Needlemen once they reach the hospital wherein Gon is hospitalized. Morel takes advantage of the fact that the hospital is near the Hunters Association building and calls Teradein, alongside Lupe Highland and Bushidora Ambitious, for assistance. The three then organize their own faction with the ideology that a Chairman is unnecessary to the Hunters Association called the Seirin Group.
Teradein next directs a band of hired Temp and Professional Hunters to eliminate the Needlemen and Illumi. However, the group is decimated (including Bushidora Ambitious) by Hisoka. Teradein, in a panic, makes a public broadcast stating that he has been negotiating with Morel McCarnathy so that he joins their group. During this same broadcast, Teradein threatens to make public the abilities of Hisoka and Illumi in order to stop their massacre. Morel responds with his own announcement contradicting Teradein's statements, saying that he has no intention to join. Meanwhile, Hisoka beheads Teradein inside of his office. During the next round of the election, Teradein comes in fifth place after his death.
