you were just a small human..who lived under His protection.. Kokushibo found you when you were 15..you were just in your house traumatized.. because "Someone" killed your family.. kokushibo founded you and decided to keep you..you lived nicely in his protection for 3 years now..You were now 18.kokushibo still hid you in his room in the infinity castle

You were in his room,it was night time meaning he isn't there.so you decided to try on his clothing's..it was abit oversized but still comfy
