Personality

Biography
Kaysis was approached by Professor Reginald Down and presented to him a drug that his student Emily Grant created that turned people into mindless beasts. Seeing this as a major opportunity, Kaysis sought to utilize the drug to attain power for himself. Together with Professor Down, they orchestrated a plan to get Emily to work for them by forcible giving her drug to some criminals in public and ultimately lead her into a situation where she would be forced to comply with his plans. To help with this, Kaysis recruited Kimberly Warren from Britain's National Security Bureau, who was also assigned to guard Emily, and have him capture her and bring her to him. However, his plan was momentarily thwarted when a unidentified thief snuck into Emily's school in order to steal some of her drug, but ended up creating an airborne leak with her drug that infected many people throughout the building.

When Emily confronted the Security Bureau, Kaysis sent several of his henchmen that were lead by Kimberly to capture her, but they and the bureau's forces were all defeated by Emily's new ally Kousuke Endou. Soon afterwards, Kaysis contacted the bureau through Kimberly's smartphone while using the alias "Odin" and demanded that they hand Emily over to him or threatened to infect many people with Emily's stolen drug. He demonstrated this by remotely detonating a capsule of the drug inside Kimberly's stomach before killing him by detonating another capsule that caused an overdose. Ultimately, they agreed to his demand and met up with some of his subordinates at a local restaurant the next day. Thanks to Kousuke's help, they managed to subdue Kaysis' lackeys and forced them to take them to his boss.

That evening, Kaysis was approached by Emily while she was escorted by one of hi subordinates Woody into his office. Once she arrived, Kaysis was immediately delighted to see her and expressed his desire to make her his woman by promising her power. Emily, however, rejected his advances with unwavering contempt, which served to only motivate Kaysis further into getting her to fall for him. Before he could make any more advances, he was confronted by Kousuke, who managed to enter the office undetected thanks to his notoriously thin presence. The security bureau arrived moments later and surrounded Kaysis. Despite this turn of events, Kaysis revealed a remote in his hand and threatened to detonate Emily's stolen drug and infect many innocent people. Kousuke, however, was unfazed with this threat, and managed to knock out Kaysis with a quick chop to his back.

Kaysis had awoken soon after, and was fully restrained. He immediately ordered his henchmen to release him, but they were hypnotized by Kousuke into making awkward poses while in front of him. Just then, Bureau Chief Sharon Magdanese approached Kaysis and ordered Kousuke to interrogate him. At first, Kaysis refused to cooperate and threatened to harm Kousuke and his loved ones, but soon became quiet when Kousuke used his hypnotizing Artifact "Staking the Pride of the Villager" to obey. At first, Kaysis was babbling incoherently while in his hypnotized state, but eventually became compliant when agent Vanessa Paradis hit him hard in the head. While hypnotized, Kaysis revealed his plan and explain that he intended to use a refined version of Emily's drug and release into to the world's supply of drinking water, while also hoping for her create a new drug that would suppress the symptoms if taken on a periodic basis, thus enabling him to be the ruler of the world. He then revealed his affiliation with the secret organization Hydra, and more more importantly the location of his drug processing facilities, as well as identifying Professor Down as is co-conspirator. Kaysis is then taken into the bureau's custody.
