The Bat Sage (Orochimaru X Reader)

Chapter III: New Home

  Few days have passed since you found the notebook. Sometimes you were closing your new bedroom's door and returning to your old home. It was not very easy for you to move between the two dimensions without being noticed but you somewhat managed it.
Besides that, Kiyoshi said that you should've start training and become a kunoichi, he almost forced his father to train you. Soon you figured out that Kiyoshi's (and now your) father, Tsuneo was known as the king of the vampire bats. He was the bat sage, trained by the god of the vampire bats — the largest bat in the world. He had a rather terrifying immortal technique — stealing one's age by drinking their blood after performing special hand seals. This jutsu could be used on any species which had blood. It was very hard to learn but also very important for surviving, that's why he decided to learn you it first.
— You must choose young prey when you'll be old, in order to stay young and never die by old age — if you'll drink blood from the old prey, you will become older. That's why some bat sages prefer to use this technique on humans — it's harder to determine the age of an animal, but it's easy for me and I'll try to learn you as well. — Tsuneo said.
— Wait, if I'll use technique on the animal which is 8 years old, will I look like child? — You asked.
— Depends on the animal... For example, 8 years old dog is an adult, you will probably look as the middle aged version of yourself or even older, if you will use this technique on the dog, which is 8 years old.
— I see... — You said as you continued training to learn right hand seals.
After a few more days you already could perform hand seals, Tsuneo started to learn you making traps, using various weapons and summoning bats. Bats weren't ideal creatures to summon, because they weren't much help during the morning, but they were good at night and you could sit on the back of a large bats and fly with them, so you liked them. You loved living in the Yami clan's .
— Onee-chan! Play with me! — You get glomped on by Kiyoshi when you were returning from the training grounds. You lose balance and fell on the ground, with him on top of you. — Oh, sorry, sorry. — He stand up and helped you, Then he picked up the notebook from the ground. — Is it yours? — Kiyoshi opened the notebook, — Why is there written Hokage's name?
