浪川大輔
is the president of the student council of Sakimori Academy and brother of Akira. He demonstrates an elite disposition, but is usually helpless in crisis situations. He was pressured by his parents to pass an exam to get into one of the best national schools. When Akira was discovered to have hacked into the exam database and later suffered extensive bullying because of it, he distanced himself from her. Later in life, he tries to atone for this by being over-protective of Akira. He marries Takahi, as seen in the epilogue. He was believed to have appeared in the futuristic scenario, but this was later revealed to be his descendant. He is voiced by Daisuke Namikawa.
