In Raw, it's already in chapter 206. In the next chapter, the security guard will help them exchange favors. The security guard said there's a secret door and how much they need the password, so Hoshimi will change the card and for that, he'll seduce Kajiwara. When they're close to having sex, Hoshimi vomits as part of her plan. On the day of entering the door, the security guard said that Kajiwara is going on a trip to Asia, so they took advantage of that day to enter with Sawaya, entering with codes that ask to enter. It turned out that the password gave an error because it was Kajiwara's plan and he always changes the password. He took the opportunity to show Sawaya and Kaede what's on the door.
