Tenma was born to Miyoko and Hase of the wealthy Hase family. As a child, he was often around Oto Edogawa, whose mother was the best friend of his. Their mothers wished that Tenma and Oto would marry someday. Sometime before or after his mother died, he and Oto were engaged.
His father was later remarried to Mirei. She cared about Tenma, but disapproved of his engagement to Oto. His parents allowed the engagement to continue, but only if Oto continued attending Eitoku Academy.
In high school, Tenma became the student body president of Momonozono Academy. He was considered their "star pupil" and attracted a lot of attention. Similar to the F4's pull, new students flocked to the school because of Tenma.
"Oto, you said it yesterday. That I would be set free. So from today on, I'm going to live how I want. For your sake, Oto. Kaguragi, she won't get kicked out if you get your donation, right? Now hear this. If you ever do this again, I'll crush you. As Oto Edogawa's fiancé."
The Correct 5'sHaruto Kaguragi and Sugimaru Eibi visited Momonozono suddenly one day. Tenma saved the two of them from beaten by the other students. He attempted to have a conversation with them, but Haruto became irritated and left. A few days later, Oto unexpectedly visited him at his home. She informed him that she was going to quit Eitoku. When Oto told him he could be "free" now, Tenma questioned if her quitting was the Correct 5's fault. However, Oto took all of the blame. Tenma then asked her, if she quit would she return to the "smiling" Oto that he used to know. She had no answer for him.
In the morning, Tenma went to Eitoku and donated $500,000 in Oto's name. He happened to see the other Eitoku students beating up Oto. Tenma swiftly threw them away from her. He looked at Haruto and called him "despicable". Taking Oto's "free" comment to heart, he declared to her that he would live how he wanted, but for her sake. Tenma stood up and told Haruto that he would "crush" him if he ever hurt Oto again. At the hospital, Tenma arranged for her to stay there overnight "as a precaution". He indirectly confessed his feelings by saying, "I never once thought of you as just a fiancee arranged by my parents." He asked for her answer, but decided to wait until she felt better.
Tenma was later approached by Airi Maya, who told him that Oto was "in danger". She evidently lured him into the basement of retail store that her father owned. Sometime later, she locked Oto into the same room. Tenma was immensely relieved to see that Oto was okay. He was also happy to be in such close proximity to Oto. After Tenma promised to protect her forever, Haruto unlocked the door. Tenma told Haruto "not to hurt Oto ever again." On their way home, Oto told Tenma that Airi reminded her of a storybook they read as children.
Originally silhouetted with curly hair, Tenma actually had light, straight hair. One of his noticeable features was a small mole just below his left eye. His overall appearance was considered good-looking, attracting the attention of females. Oto even described his face as "beautiful".
