Twenty-four hours had passed since they were transported to Middle-earth. That was the moment when Koyuki appeared from the ceiling of the Hinata residence in order to have a visit. She wondered why she found the house empty. "NATSUMI-SAN? FUYUKI-SAN? DORORO? KERORO-SAN?" she called loudly. Unfortunately, she didn't hear any answer. She decided to check Keroro's room.
Koyuki found the room empty. Not giving up yet, she continued by checking their secret base. Their meeting room was also empty. Finally, she went into Kururu's lab. She found some pieces of a broken invention. An hour later, Aki came into the lab on her attempt to find her missing children. "They're not here," said the ninja. "How long have they been gone? Where are they?" asked her. "If I know it, I'll tell you. Sorry," she apologized. Then, Aki permitted her to go home.
Aki was very sad. She imagined Natsumi and Fuyuki were dead along with their alien friends in an explosion as she looked closely to the destroyed device. "If only I can be together with them... Flesh of my flesh... blood of my blood... Natsumi, Fuyuki..."
The doorbell rang when she was having her meal. It was Baio Nishizawa, Momoka's father. "Is my daughter here?"
"No one here but me alone. I lost both my children, I found a broken device that might had exploded."
"I'm sorry. Where is it? Show it to me."
They went down to the lab. Baio felt that his dear daughter had been killed by that device made by Kururu. "Paul said to me that she visited this place yesterday morning," he informed.
Their conversation was interrupted by an alarm sound coming from their meeting room. It was a call from Garuru's Platoon. Aki answered it and said that they were not available at that moment. "Thank you for your information. We will come to your house shortly after I end this call," replied Garuru.
A few minutes later, Garuru and his subordinates arrived at the secret base, they found that what Aki told them was true. They couldn't find Garuru's brother and the other Keronians there, so they began to search that secret base.
Tororo called them all to come to Kururu's lab after he found a clue. "This seems to be a device used for teleportations. I wonder why Kururu made this one."
"Did you say teleportation? They might be transported to another place. I'll call Paul and request him to order the army to find them. You, try to fix that device, it might works," said Baio to Tororo.
"Okay, okay. This is such a complicated one, damn you Kururu! Yes, it might works, but I need a few weeks to finish this one. You better leave and do your daily activity. Give me your number, so I can notify you if I'm done with this," replied the salmon-colored Keronian tadpole. After Baio gave his number, he left the house. "Good luck with that!" said Aki, encouraging him before she left the lab.
