"I promise." said Kai and left Sensei Wu.

The next day Sensei Wu didn't hear any news of the police finding Que so he felt very troublesome like everyone else. Today was Cole's turn to teach Mitsu, he took her out on a hike and they returned about five hours later.

"Maybe that was a little too intense for my second day of training." said Mitsu as Cole blushed.

"Oops..."

"Don't worry I was just joking!" said Mitsu as everyone laughed.

"By the way... Today is Mitsu's turn to cook. Am I right!" said Jay as he playfully elbowed Kai.

"Mitsu you don't have to cook, I will cook for you. You've been through a lot today all you need is some rest and hot tea" said Kai standing up.

"No no, I wouldn't let you do something like that for me. I can cook but thank you for your offer Kai." said Mitsu and smiled ta Kai.

"I should protect Mitsu, that's what Sensei told me." thought Kai.

"What would you like toda-" Mitsu was interrupted by a red siren going off. "What's that?"

"That's a red siren if it goes off then Ninjago City needs us." said Nya as Kai, Jay, Lloyd, Zane and Cole put their hoods on.

"Can I maybe watch?" asked Mitsu.

"No, you're not ready yet, stay here and take care of the ship." said Kai as he jumped of the boat and down the anchor.

The ninja flew their dragons to the city, but everything seemed to be peaceful. They landed on the nearest building and looked around no-one was in danger or needed help.

"What's going on? I thought Ninjago City was in danger." asked Jay, "Nya?"

"But the siren... It went off, it has to be something." answered Nya nervously.

"There is nothing, can't you see it?" said Kai looking around once more.

"I know, b'but the siren never lied before"

"Maybe something's wrong with it. You can fix it later, let's go." said Lloyd and jumped down the building summoning his dragon, flying away. So did everyone else.

It was already night when they finally reached the bounty.

"I'll go fix the siren then." said Nya an ran towards the control panel.

"Where's Mitsu?" asked Kai.

"She's gone." said Sensei Wu looking down.

"But how, she was with all the time, right?" asked Kai looking puzzled.

"At one point I went to meditate on a hill and left her alone on the bounty, when I came back there was no sign of her whatsoever. It is my fault that the Mitsu left us."

"Or maybe she didn't leave us... She was kidnapped. The siren was all a trap so Que could get us out of the way, she than waited until you left to meditate and took care of Mitsu. She can be anywhere now! We should find her."
