Everyone ate their breakfast with smiles as they talked about their cheerful day with Maki. It boosted everyone's moods and hope filled their hearts as they prepared for the next part of the motive.

A loud shriek made everyone jump in fright and watch as Shirogane dropped her glass of juice, making it splatter across her uniform. Something large scurried across the table, making a few others shout and scramble away from the table to put distance between them and the spider. Saihara and Ouma began to laugh as they watched everyone rush away, sharing a high five in victory. Gokuhara gasped and grabbed the spider with gentle hands. He handled it like a newborn child, giving the spider a small pat before taking it away to his lab.

"You've changed, Sidekick," Momota muttered as he watched Saihara laughing about his prank.

"Yep!" The detective grinned at Ouma who finally had a smile of genuine happiness on his lips.

Shirogane grimaced as she stood up, the sticky juice soaking into her clothes. "I need to change..." She made her way to the dining room door, only to open it and find someone else on the other side. Someone the same height as Shirogane stared back with glowing crimson eyes. They gasped and took a step back, seeming frightened to see the blue-haired woman. Everyone stared before they ran away, their skin glinting slightly in the hallway light.

"Was that... Kiibo?" Yumeno muttered as she looked over at the Ultimate Robot. He looked around at everyone nervously.

"We should chase down baby Kiibo so he doesn't blow up the school!" Ouma laughed, leaning back in his chair with his hands behind his head.

K1-B0 shook his head. "That is a highly unlikely outcome, Ouma."

Everyone remained quiet, trying to process what they'd seen. "Kiibo, forgive me for asking, but could that be your younger self?"

The robot sighed, sadness filling his teal eyes. "Technically, it's not me. It's one of the prototypes that came before me, so he's my older brother if you see it from a human perspective."

"One of?" Hoshi repeated. "How do we know which prototype it is?"

"By their name." K1-B0 noticed everyone's expressions of confusion, so he decided to clarify further. "Each prototype had a different name since the professor saw us as different people. It seems like my 'child-self' is a prior prototype."

"I bet it's called Jiibo or some stupid shit!" Ouma began to laugh, only for Saihara to flick his forehead.

"That's robophobic!" Kiibo shouted before taking a deep breath to calm himself. "Anyway, my prior names were Kiko, Nen and Nozomi, respectively."

"Only three prototypes?" Harukawa asked, her brows furrowing in thought.

K1-B0 beamed with joy when he had the chance to explain. "The professor is smart and made little mistakes when creating us!"

Everyone turned to Momota as he cleared his throat dramatically. "Let's figure out which prototype it is so we know what he's capable of. Can't have him malfunctioning, can we?" People agreed, so focused on beginning the search that they missed Harukawa muttering that she mentioned the idea.

K1-B0 searched the warehouse with the help of Akamatsu and Harukawa. Everyone decided to split off into groups after a warning from K1-B0. He knew that if K1-K0 happened to be the one present, they might spontaneously combust, so they needed to be found as soon as possible.
