Born sometime in the 20th century, That Man experienced the Dawn of Revival firsthand.[24] At some point, he became a disciple to The Original,[14] one of the five closest to him.[25] Not long after Chronus and the others formed the Conclave,[25] the Original returned to the Backyard[14] in order to stop the Universal Will's rampage. In the process, he retrieved the seeds of the Absolute World and entrusted both items to That Man.[25] The five disciples would await the Original's return, but began searching for a way to stop the Universal Will on their own; That Man, at odds with the other four, chose to "educate the people and help them evolve".[14]

That Man Story
Illustration with NAME_1 and NAME_2.

A gifted prodigy, That Man completed Biology studies in his youth and played a part in completing the Theory of Magical Science. Specializing in the field of Bioinformatics,[4] he met NAME_3 and NAME_4 in college,[26] who would become his best friends.[27] In 2014,[28] That Man was transferred to the Ecosystem Evolution Project to spearhead applied magical research[4] under his former professor NAME_5 NAME_6.[29] That Man would often discuss philosophy with NAME_1.[4][30]

In 2015,[20] presumably succeeding NAME_5 as the project's director at this point, That Man completed the NAME_7 cell theory,[28] managing to stabilize cells infused with magic.[20] Afraid of their weaponization, That Man turned his research to the state under four conditions.[20] Following a successful negotiation,[31] it was renamed the NAME_7 Project[32] in 2016,[28] yet the military soon intervened. Forced to work for them, That Man resisted the way he could:[33] he convinced the terminally-ill NAME_2 to cryo-sleep, and planted one of the seeds in NAME_1,[34] restructuring him into a NAME_7,[7] gambling for his friend to survive.[33] When confronted about it, That Man lied to NAME_1, and left him for dead. At his apparent betrayal,[35] NAME_1 swore revenge.[6] Months later,[36] That Man went missing,[28] causing all projects to be frozen, and all related data to be classified.[31]

After the U.S. reopened the NAME_7 Project in 2042,[31] they were able to successfully activate their own NAME_7 prototype in 2045.[28] Secretly opposed to NAME_7's weaponization,[14] That Man joined this new project under an alias,[28] in order to build a collective information system to give orders to the Gears.[14] After their mass production began in 2065,[28] That Man created Justice in 2073,[37] transforming NAME_2 into the basis of the Commander G
