Hiro Adachi is the main character on this history. He is a Japanese student who studies on a study year abroad programme. He he is 20 years old. He recently broke up with his girlfriend named Akiko, so he decided to go to Berlín alone on summer holiday.

Hiro is very sentimental, he usually remembers things about his past and feel lonely. He is also a serious and quiet person. Sometimes he doesn't know what to do or which way is the best for him. On the other hand, he is very fearful and suspicious with strangers. He is also very observer.

Hiro likes to read an American thriller and practice his English. He doesn't like people with mysterious personality.

His ex-girlfriend, Akiko, was on the same course in England as him and their relationship was perfect, without any fights between them. But then, everything changed and she started to get jealous about a dog. They broke up because Hiro has a photo of Yuki, his golden retriever dog, on his screensaver and that's why Akiko  got angry and said she didn't want to see him again.

I liked when he said that he is not going to be sad anymore, he won't look back and will have an exciting and adventurous holiday looking forward from now on. It's my favorite part because finally he took a good decision and realized what is the best for him.

Once on the platform, Hiro moved back from the edge of the platform but the Shark took his arm and helped him. After that, Hiro climbed the new train and left the Shark behind.
