Masamune Dan

"Can you stop my son?"

- Dan asking Emu if he could stop Kuroto before revealing the truth to him.

Masamune Dan (檀 正宗) is the former CEO of Genm Corp. and the father of Kuroto Dan. He had been imprisoned after being framed by his now corrupted son, using Masamune as a scapegoat into making everyone believed he started the Zero Day, until it is finally made to public in the present.

Masamune later re-emerges following the resurrection of his son and joins the game by using the Kamen Rider Chronicle Gashat with the Gashacon Bugvisor II to transform into Kamen Rider Cronus (仮面ライダークロノス).

Early Life
16 years ago during Emu's surgery led by Kyotaro Hinata where he and his son Kuroto were involved in, his son had first discovered the Bugster Viruses which first appeared glitching his laptop. A few years later, the Bugster Virus was later triggered by Kuroto during Zero Day, while Masamune was framed for it and later imprisoned.

Present
Masamune was visited by Kiriya Kujo in his prison. He would later give the information about the truth of Zero Day to Kujo, which led to Kujo's death at the hands of Genm Zombie Gamer Level X, who was his own corrupted son.

One day, a cop named Heiji Uesugi went to visit him and talked about that the case of Zero Day has not been solved, and two people (Kuroto Dan and Kiriya Kujo) that have something to do with him have been missing. He told the cop that he had nothing more to say to him, and turned away to go back to his cell. As the cop insisted to find out something, he suddenly gets symptoms of Game Disease and starting to become weak, which caused him to turn around in confusion.

Later on in the same day, Emu Hojo, accompanied with Asuna Karino went to visit him. When Emu introduced himself, Dan was a little bit surprised. He asked Emu what did he come for, which Emu told him about Kiriya's death during last year's Christmas was caused by none other than his son. Hearing this, Dan said he was truly disappointed by his son's doings. Emu then asked Dan about what he said to Kiriya during that day, which Dan not only replied to him about the truth that happened in the past, but also making a request to Emu to stop his son's sinister plans.

Becoming Cronus and Showing the True Color
Months later, Masamune was finally released from jail and took over Genm Corp by force. Ren showed his protest in gentle manner which Masamune also took it gently. When the Riders and the Bugsters finally have their final clash, Masamune showed himself using the power of Cronus. He later told everyone that everything had come just as his plan. He reveals that the manipulation on himself to be jailed, the perfection of Kamen Rider Chronicle, and the succession of Kuroto were part of his plan; making Kuroto actually his hidden pawn and not Kuroto who pulled the string, which surprises Kuroto himself. He then transformed into Kamen Rider Cronus, surprising the riders as Kuroto had told Emu, Hiro, and Taiga that it is almost impossible even for the Riders with exception of Emu as he had a chance, to control the power of Cronus as the payment is huge for the controller's life especially immediate death for those who didn't receive operation of Bugster immunity. He told the others that Emu is not the only "the first infected Bugster" and claimed himself to be "the other one".

Parad, Ren, and Graphite were vexed on this especially because the Riders were defeated single handedly with his power to control time. He also defeated Parad and Graphite, killing Ren permanently as he stopped the time of life of the Bugster whom he eliminated. He left all of them and announced that he is "the true God" starting from there.

Personality
As a father, he cares about his son and had a great relationship between each other. He also had high expectations for his son to do something big when he grows up.

That is until his son became corrupted for the sake of completing the ultimate game, which is Kamen Rider Chronicle. His son framed him that he was the one who started the events of Zero Day that happened five years ago to cover up the fact that he was the actual criminal who started those events in the first place. This eventually drove a wedge to the father and son relationship, causing Dan to be disappointed for what his son had become.

He became even more disappointed when Emu told him that the death of Kiriya was caused by none other than his son. After hearing this, he decided to tell Emu the truth that happened in the past and made an offer to Emu to stop his son once and for all.

Or so it seemed. After being finally released from jail, he forcefully regained control over Genm Corp. despite Ren Amagasaki still being the incumbent president of Genm Corp. Later on, he showed his true nature that he actually "the other first infected" when Emu was infected and showed to everyone that he is capable to use Cronus' power despite Kuroto's worry of the ultimate price. He already planned everything all along to have his son for perfecting the ultimate game and actually indirectly making his son to eliminate anyone who interfere of creating the game.
