Daisuke Dobashi
Chronologically speaking, Daisuke Dobashi (土橋大介, Dobashi Daisuke?) started having the moon dreams first, as he started having them when he was seven (Rin recovered his memories at an even younger age, but at a later time, since Rin is much younger than Daisuke). Daisuke spends very little time on-panel in the manga, so not much is known about him. However, he does not trust Haruhiko, whom he believes to be Shion. He is also the only one who realizes the danger that collecting all of the passwords would pose, making it much more difficult for Rin to collect them all.
His previous life, Hiiragi, was the team leader. Hiiragi was not shown to do much, and most day-to-day administration of the base seem to have been made by consensus or by Gyokuran. Despite being the base leader he shows up rarely in flashback scenes, even in the long stretches of flashback, both from Shion and Mokuren's perspective, detailing their days before arriving at the moon base, the daily goings on at the moon base, and when the situation starts deteriorating on the moon base after the Homeworld is destroyed. Hiiragi's most important function in the plot was his executive decision to forbid the scientists from evacuating to Earth after their homeworld was destroyed. Hiiragi was the third scientist to die.
