Jo wasn't in the PTGS group before and when she came back, Akihiro has already set up the private A-9 team and let her join. Most of the members were familiar to Jo, and some of them were new to her.

He has a funny attitude on the happy side and on the dark side, and he could not give up on the clues of solving a case as well. Elsewhere, he also stores his teaching side as a very curious man. Sometimes he is mistaken on something as he shakes his head in a very funny emotion.


Akihiro used to be an artist since their whole family were artists.

Hase Seiji (Wife)

Akihiro first met Seiji since he was 17 years old. They met again in the same college, both taking their major course of arts and crafts. Despite that she had a boy name and due to him having the same tastes as her, they become best friends and even formed a relationship. Little did he know that applying for a police college at the same time as his original college kept as a secret to himself will lead to arguments. When Seiji found out that he was attending two colleges, she immediately felt emotionless because in her family timeline, they had always had strong distastes towards the police force. However, Akihiro cleared things up and the two of them formed a happy family of 5.

Takayama S. Akane (Eldest Daughter)

Akihiro's first daughter, Akane, was born with brilliant intellects. He knew that by looking at her, being able to read what her future could result with. When they were still a group of artists as a family, Akihiro taught Akane how to read and draw mangas, get them published, and even broadcast it into an anime. Despite only being drawing mangas and characters, Akane was more interested in beautiful scenery and landscape work, and Akihiro only had to teach her how to make a beautiful masterpiece.

Akota is probably Akihiro's best daughter, or thought to be. First of all, he warned Seiji that she had to birth a boy, but again, she birthed a girl. Akihiro has never been mad before, but he does appreciate Akota and taught her many things, such as animations. He also respects Akota's best friend Shuang Wen Zu because that is one of his best students in PTGS group.

Takayama S. Aiko (Youngest Daughter)

Aiko is somewhat similar to Akota, except that she behaves more like a brat and often is rude to others. But that's when Aiko doesn't like something. Akihiro taught her easy and basic art.

Jo (Student)

Takayama used to be a regular commander in corporals when DO did not start having levels of A, B, C, D, F. His first best student was Jo because she seemed to be the only girl out of the rest to have passed certain levels. But he didn't know, nor did the class, that she quit mysteriously back to college to take full courses again.
After coming back from college at the age of 28, she joined DO again only to have known several changes. Akihiro saw Jo's return but didn't fully recognize her. For several attempts, he realized that it was his long time no see the best student from years ago. He talked to the police chief about moving her to A-9 and it worked. From then on, Jo became his second best student and based on the leader position.

Code (Student)

Akihiro was not lucky at first for not noticing a person like Code. In his training, he received high-level certificates and passed to A-8 immediately; he had skipped F, D, C, and B. After that, the police chief placed him to be the first member of the developing private group A-9. Akihiro did not understand his problem and did not trust the police chief that he already made a decision of moving a supervisor to A-9. But Code proved his abilities to the commander and got the title of the first leader in the PTGS group. It is shown that Akihiro now accepts more of him and even says that Code is his first best student.
