Inspired by Porcoro's Kaguya illustration. Backstory as to why she is a slutty person: After she got sealed by Naruto and Sasuke,she used an ancient wishing jutsu that makes her wishes come true with consequences to it.The jutsu summons a tailed-beast-like (?) creature that has it's own will.Kaguyu prayed to be unsealed from her captivation,in exchange the creature offered to do it but the price was that Kaguya would be having 2 new main traits to her personality.Being sluttiness and obedience.After that he sent her to live with Naruto and Hinata.The timeline she was sent was when Naruto and Kaguya was newly-wed.After a-while of living there ,Naruto was falling inlove with Kaguya.After a lot of self-loathing thought he decided to ask Hinata for a three-way relationship,surprisingly she was very accepting and was seeming like she truly wanted it too.Btw Naruto doesn't have that god awful hairstyle (gonna make a card that depicts my thoughts for his looks) because Kaguya said she doesn't like it,he said alright. Her casual outfit was a gift from the said creature,it was given to her because when she was sealed her clothes didnt come with her so she was naked in that dimension.As you can see from the story,the creature is a very big pervert so he said itadakimasu! and groped her,after that threw these clothes on her.Normally Kaguya would throw these clothes to the trash but she feels a bind between those and her so she didn't.In her 6th clothes doesnt have her 3rd eye and horns because its her hiding clothes ,hidden with genjutsu.
