## Characters
### Minato Kohichi (湊 晄一)
He came from the same future world line as Haruna. A weapon (bionoid) developed by a military research institute during the interstellar war. For some reason, he came to the past Earth with Dr. Bakuroi, the person in charge of the Bionoid Development Project.

The weapons that were in the process of being cultivated were still in their infancy, and in today's world where there is no equipement, there was no decision but to raise them as normal humans. But the doctor, who has just passed the the time limit and has no power, decided that raising them by himself would be impossible. He decided to leave the baby in the church. Shortly thereafter, he was adopted by the Minato family and given the name Kohichi.

### Toujou Lena (東條 レーナ)
Because she's aiming to be a novelist, she writes novels in her spare time. She likes to read books and reads so much she needs glasses. As for the ribbon on her head, it was her father's first present to her, and even when it broke she bought a similar one and wears it daily.

Her father is a novelist. Serious, tough, and stubborn. Her mother was German and died while giving birth to Lena in Japan. After school, she spends most of the time in the library (or a used book store, when she's not on duty). She is also good at repairing books.

### Abiko Harutaka (我孫子 晴孝)
He originally wanted to become a motorcycle police officer, but gave up because he was too antisocial. He's currently a detective in the Mobile Investigative Corps. Even he had a period where his heart wavered. He has a lot of qualifications, so he can often say, "I can't do this right now."

There is no consistence, but he became a qualification maniac after his parents told him to get  a qualification that would give him an advantage when taking the police recruitment exam.

### Sakura Shino (保育 徦)

He went to a private high school where he got below average grades, then went to a flower design school. He curently works in "SAKURA fleur," which is run by his parents.

Having a flower shop has been his dream since he was little, so every day is fun. He often bleeds from his mouth, probably because his body is weak. He's clever and cheerful, a popular person who is kind to everyone. His motto is "Get help from people who are good at what you are not good at, and vice versa."
