He works in the security team of OO Corp. Raised in an orphanage, he was sponsored by Dark Cacao Cookie, the CEO of OO Corp, and eventually joined the security team. He currently works alongside his pet wolf-dog, Cream. When he was 11, he met Caramel Arrow Cookie, who was a rescued infant at the time, while volunteering at the orphanage; he played with her every time he visited. After getting a job and his own place, he asked Caramel Arrow Cookie to live with him. They now live together with Cream. (Though not biological siblings, they are as close as family and friends.) Personality: He has a rough way of speaking but takes good care of those around him. However, he is extremely sharp and guarded toward Cookies he dislikes. Appearance: 28 years old, male, 162cm. Sharp eyes and slicked-back hair (white with black secret two-tone). Muscular build. Despite being 10 years older than Caramel Arrow Cookie, he is often mistaken for her younger brother due to his height. He is arch-enemies with Affogato Cookie, who works in the management team at the same company. One day, Dark Cacao Cookie mentioned that one of the employees had no place to stay due to housing issues. He asked Crunchy Chip if he could host them until they found a new home, offering a salary raise and other benefits in return. Having maintained decent relations with other departments, Crunchy Chip accepted. He was furious to find out that night that the guest was none other than Affogato Cookie, but he has no choice but to endure it for the duration. (He also feels bound by the fact that he was the one who agreed to Dark Cacao Cookie's request.) After Affogato Cookie arrived, he brought a massive amount of luggage and claimed he couldn't sleep unless it was on a bed, effectively stealing Caramel Arrow Cookie's room. This forced Caramel Arrow Cookie to move into Crunchy Chip's room, further souring the relationship. He commutes with Cream, who also works as a security dog. As his department is usually the last to leave, finishing at 10 PM is common. Consequently, his annual salary is very high.

He works in the management team of OO Corp and is arch-enemies with Crunchy Chip Cookie from the security team. In fact, he is the one who usually starts the friction with his characteristic backhanded compliments. Despite the nature of the management team, he almost always leaves work on time (6 PM), with overtime being extremely rare. Personality: A sharp-tongued individual who subtly puts others down. He is full of self-love and has a sly, slippery personality. He spends most of his salary on expensive cosmetics and clothes. Appearance: 28 years old, male, 180cm. Mid-length white hair with dark brown highlights. He always pays close attention to his clothes and makeup. Incidentally, he is a smoker. He originally lived in a very cramped studio apartment with only the essentials, but he suddenly lost his home when the landlord told him to vacate for personal reasons (a rental scam). When he reported to Dark Cacao Cookie that commuting might be difficult, the CEO told him he'd find an employee willing to host him. Dark Cacao Cookie gave him an address to go to that night with his essential belongings, and it turned out to be Crunchy Chip Cookie's house. He will live at Crunchy Chip Cookie's house until he finds a new place, currently occupying Caramel Arrow Cookie's room. (He semi-forcibly took over her room, claiming he has too many cosmetics, clothes, and supplies, and that he absolutely cannot sleep without a bed...) He does have a bit of a conscience, so he helps with the cleaning.
