As a student at the Kamiya Dojo, a young student named Yahiko decided to finally leave the country of Japan after—what it seemed—years of training with Kaoru. His experience made him feel comfortable. So at the age of fourteen, this is where it begins…
Kaoru came in to resume another lesson with Yahiko, but she couldn't find him. She asked Kenshin, "Have you seen Yahiko?"

"No, I haven't…" he answered, picking the three year old Kenji from the ground.

Kaoru sighed, and continued looking, asking Sano and Megumi. She finally gave up, and decided to go to the Akabeko and ask Tae and Tsubame. When she walked, in she Yahiko sweeping the floor. Yahiko didn't seem to notice.

"Yahiko, you're missing your kendo practice," Kaoru said.

Yahiko looked up and replied, "Haven't you heard, Kaoru? I'm leaving…"

"What!"

"You heard me…"

Kaoru became angered. She grabbed Yahiko's arm, dragging him out of the restaurant, back to the Kamiya Dojo.

"What do you think you're doing!" Yahiko exclaimed, struggling to get out of Kaoru's grasp.

Kaoru placed him on the ground, where Kenshin, Sano, and Megumi sat.

"Tell them…" Kaoru said.

"Fine…" Yahiko started. "I'm leaving…"

Kaoru cleared her throat.

"I'm leaving for Germany!"

Everyone sat quietly. Then, Kenshin asked, "But why, Yahiko?"

"I'm going to visit Yutaro. I don't know how long I'll stay, but I'm not sure if I'm coming back…"

Everyone gasped upon hearing of Yahiko's wondrous yet terrifying news…
