Kosu left the Adventurer's Guild, feeling determined to find Jinpei and rescue him from whatever danger he might be facing. He knew that it would be a difficult journey, but he was ready to face any challenge that might come his way. However, the first thing he needed to do was to get some information about Jinpei's whereabouts.

He went to the hospital where his friends Sakura and Ryota were being treated. He wanted to say goodbye to them before he left, and perhaps they could give him some clue as to where Jinpei might be.

As he walked into the hospital room, he saw Sakura and Ryota sitting up in their beds, looking much better than they had when he had last met them. Kosu was relieved to see Sakura and Ryota on the road to recovery. He had been worried sick about them ever since the incident with Dr.Kuro and the Black Sun organization. 

Kosu greeted Sakura and Ryota warmly, and they exchanged stories about what had happened to them since their explore in the icicle dungeon. 

After a while, Kosu brought up the subject of Jinpei. "Do you guys know anything about where Jinpei might be?" he asked.

"I'm sorry, Kosu. We wish we could help you find Jinpei, but we don't have any leads," Sakura said apologetically.

"Yeah, we were all knocked out since that battle with Black Sun. We don't even know what happened to Jinpei," Ryota added.

Kosu nodded, understanding their situation. "It's alright, I'll find him somehow. You two just focus on your recovery and get better soon."

As Kosu turn to leave, Sakura talk to him. "Wait, Kosu. We don't have any information about him. But you might want to talk to Dr. Yamamoto. He might know something."

Kosu was surprised. "Dr. Yamamoto? Why would he know anything about Jinpei?"

Ryota spoke up. "Well, it looks like they've known each other for a long time. They had a bit of a falling out, but they might still be in contact. You should talk to him, Kosu."

Kosu nodded. "Thanks, guys. I'll go talk to him."

He left the room and went to the reception desk to ask for Dr. Yamamoto's office. When he got there, he knocked on the door and waited for a response.

"Come in," a voice called out.

Kosu entered the office and saw Dr. Yamamoto sitting behind his desk, looking up from his paperwork. He looked surprised to see Kosu.

"Kosu, what brings you here?" he asked.

Kosu hesitated for a moment before speaking. "I'm looking for Jinpei. Sakura and Ryota said that you might know something about his whereabouts."

Dr. Yamamoto sighed and leaned back in his chair. "I'm afraid I don't know where he is, Kosu. The last time I saw him was when we were trying to fix his magic particle high density, and I haven't seen him since.."

Kosu's heart sank. He had hoped that Dr. Yamamoto would have some information about Jinpei. "Do you have any idea where he might have gone?" he asked.

Dr. Yamamoto shook his head. "I'm sorry, Kosu. I don't know where he might have gone. But I do have a suggestion for you."

Kosu looked at him, hoping for some kind of clue. "What is it?"

Dr. Yamamoto leaned forward and spoke quietly. "There's a place where Jinpei used to go when he needed to clear his head. Maybe you should check there."

Kosu sat up straighter in his chair, his heart racing with anticipation. "What? How? Where?" he asked eagerly.

"Well, it's near his hometown. Jinpei's family lived in a small town outside of the city," Dr. Yamamoto explained. "I remember him talking about it once. He said he used to go there when he needed to clear his head or get away from everything. It might be worth checking out."

Kosu felt a glimmer of hope in his chest. "Thank you, Dr. Yamamoto. I'll go there right away."

The doctor nodded, his expression grave. "Just be careful, Kosu. You never know what you might find."

Kosu stood up, feeling grateful for the doctor's help. "I will. Thank you again."

As he left the hospital, Kosu felt a mixture of excitement and apprehension. He was getting closer to finding Jinpei, but he had no idea what he would find in his friend's hometown. Would Jinpei be there? Would he be safe?

Despite his fears, Kosu knew he had to keep moving forward. He got in his motorbike and set off for to Jinpei's hometown, determined to find any clues that might lead him to his friend.
