17 years old. Student of Aoba High School. Daisaku is a genius of robotics and is the creator of the robot who won the scholastic competition launched by his school. After the first Derinjer attack, his robot was developed and transformed into α Robot in Professor Mizuki's Robot Center. Of the triplet that makes up Albegas's crew, Daisaku is the sunniest and extroverted addition to being the leader of the team and the main super robot pilot. In addition to the passion for robotics, he is also the captain of the high school football team, which is why he has a fan club of female students following him (often inducing Hotaru jealousy).
