Kaguya Otsutsuki Submits, Returning to the Uzumaki Clan's Homeland / The Traditional Welcome Ceremony, Kaguya Otsutsuki's Embarrassment and Anger

From this, it was clear that

the Ōtsutsuki Clan's Branch Family and Main Family system was probably even harsher than that of the Hyuga Clan...

Ōtsutsuki Kaguya Submits and Returns to the Uzumaki Clan Compound

"When I arrived in the Shinobi World, I was supposed to be sacrificed to the God Tree. That was my role as a guardian."

"But I couldn't accept dying like that. I was more talented than Ōtsutsuki Isshiki, yet simply because I was born into the Branch Family, I had to become nourishment for the God Tree..."

"So at the last moment, I caught Ōtsutsuki Isshiki off guard, beat him to death, and threw him to the God Tree."

For the first time, Ōtsutsuki Kaguya's voice rang with resentment.

Clearly,

she loathed the whole Branch Family and Main Family system.

"After eating the God Tree Fruit, I attained Kekkei Mōra and cut off contact with the Ōtsutsuki Main Family."

"To have enough strength to resist them when they came, I cast the Infinite Tsukuyomi and used the God Tree to mass-produce humanoid weapons—White Zetsu."

"But Hamura and Hagoromo were led astray by the Shinobi World's natives and betrayed me."

"In the end, I was sealed on the moon for thousands of years."

"That's everything."

Ōtsutsuki Kaguya said it all in one breath, holding back nothing she knew.

"You actually thought you could use White Zetsu to fight the Ōtsutsuki... You really are something else."

They weren't even as strong as Chunin.

Thinking they could fight members of the Ōtsutsuki Clan was pure fantasy.

"You!"

"It was the only solution I could think of at the time," Ōtsutsuki Kaguya said
