"Who are you?" The batman asked, well more so ordered.
"You can call me Saigo no Kage," (Last Shadow) the masked woman said, "or Neko, whichever you prefer, or you could keep calling me Cherry."
"What is your real name?" The bats interrogated.
"No need to treat me like an enemy, after all, we both have the same goal, and I am merely enforcing the law in which I and the other men you saw abide by," she taunted.
"What law?"
"We don't exactly abide by the laws you abide by and I am merely executing a command given to me a while ago," She said waving her hand in the air dismissively.
"What laws?"
"Why don't you stop the shipment, and I'll wait right here until you get back," she said pulling out a small orange book from a pouch on her hip opening it up and reading it.
"I'll like to continue the interrogation in the Mountain. Aqualad, you and your team deal with the shipment, meet back at the mountain for debriefing," he commanded.
She put her book back in her pouch and held out both wrists. The Green Lantern held out his ring and made a chain with handcuffs on the end around her wrists. She giggled softy, "It's almost like chakra," she whispered.
The Green Lantern started walking and she fallowed with no complaint. They walked to a old phone booth and Batman started tinkering with it. He then walked in. Green Lantern fallowed with Sakura right behind him. The rest of the league fallowed. They deposited her into a small white chamber with a small white bed. The door slid shut behind her. She walked to the far corner and sat down holding her head up. She pulled out her book and continued reading.
The league gathered in front of the computer and pulled up a screen with a video of the room. "I don't know what to make of her," Wonder Woman said.
"Neither do I," Green Arrow said.
"I think she is some sort of assassin," Captain Marvel said.
"I don't think so," Batman said.
"Why?" Flash asked, "All clue point to her being that."
"We need to ask the Young Justice League a few things before we can come to any conclusions," Batman said, "I also believe I have seen her before, a really long time ago."
"When?" Superman asked.
"I believe around twenty years ago," Batman said to the only other leaguer who knew his identity.
"What makes you believe this is the same person?" Hawk Woman asked.
"She looked and acted the same," Batman said.
"So, she might be a relative," Hawk Man said.
"Let's look up her uniform, maybe it will give us another clue," Martian Manhunter suggested.
Batman began typing on the computer pulling up the pieces of her costume and looked them up by the image. "Clothing matching material and design were found in an archeological dig in Japan of the ruins of an ancient civilization. The most likely cause of destruction was warfare," The computer said, "This is considered one of the greatest mysteries of Japan. The mystery village is also open for guided tours and picnics."
"I have a feeling she is a descendent of someone from this village," Batman said.
"I'm surprised. Wouldn't they know more about the people and culture?" Zatara asked.
"Yes, one would believe so," The Manhunter responded.
The girl in the room looked up from her book and mouthed something at them. The computer voiced the entering of the team.
"We need to ask you a few questions before we interrogate her," Batman said.
"Okay!" Robin said enthusiastically.
"When did you guys first notice her?" Batman asked.
"She kicked a rock at my head, then appeared infront of me-, "Robin retold getting cut off by Wally,
"She appeared in front of Rob really, really fast and told us to run or call for back up because she couldn't hold them both off," Kid Flash rushed through.
"She than disappeared and began fighting the man with the red eyes. She made a copy of herself, while holding her current opponent off, to fight with the masked man. She opted to knock the guy out than to kill him while she had the upper hand. She then turned to the other man, as he cut through the copy of her. She than fought until you arrived. You know the rest," Aqualad finished.
"Ah," Batman said walking away toward the holding room.
As he entered she continued reading. Her voice filled the air as she asked, "Do you remember me? I remember you. I have got to say, I did not expect you to become an avenger."
"Where are you from?" Batman asked his voice laced with nothing but demand for an answer.
"Konohagakure," She answered.
"Where is that?" He demanded.
"You would call it Japan," She responded, "Actually when the archeologist dug it up, she called it the mystery village. She still doesn't know that there were more, before they sunk."
"What do you mean?" Batman asked.
"After the fourth great shinobi war the majority of the great nations sunk into the ocean; it would have been better if they all did though," Sakura said.
"How old are you?" He asked.
"Older than you, by a lot," she responded.
"Give me a number," he ordered.
"Oh, the village was destroyed about four thousand years ago, I was fifteen, so about four thousand and fifteen," She answered.
"What are your intentions?" He demanded.
"I am… fulfilling my hokage's dying wish," she answered, "to kill the people who destroyed the Shinobi Nations."
"Thank you," He said standing up and walking out of the room.
She looked at the door in thought and then pulled her book from her pocket and began reading once again.
"What do we do with her?" Superman asked.
"She would make a great ally," Batman responded.
"What did you find out about her?" Robin asked.
"She is older than all of us," Batman said.
"I say she joins us," Flash said.
"How old does she look?" Green Arrow asked.
"Why?" Batman responded.
"If she looks young enough we could place her with the team as an mentor that would monitor them and help them improve," Green Arrow replied.
"True," Batman agreed, "She looks only slightly older than Robin. She can join the team. Are there any objections to this plan?"
The whole group shook they're head no. Batman nodded once and began walking back to the holding room, the two leagues behind him. "Neko, will you join the Young Justice League?" Batman asked.
"On one condition," She said, "When I see the man I need to kill, you will not interfere and allow me to kill him."
"Fine."
