Takeyasu Roma (路万 健康) is the president of the Astronomy Club. He has always had a poor constitution and is generally very weak and often spits up blood or passes out after doing something strenuous. He has an intense love of astronomy, akin to Mihoshi's own enthusiasm. After graduating, he goes to college with Ayumi Oumi, a girl with the same passion for astronomy as him, and who has a crush on him.
