H2O -Footprints in the Sand-

H2O's story revolves around Takuma Hirose, a blind young male junior-high school student, though the cause for his blindness is undetermined. After his mother died an unexpected death, it left a deep emotional scar on him, which caused him to become very lonely and reserved. Due to this, Takuma and his uncle move from the city out into a rural area and Takuma is enrolled into a new junior-high school. At his new school, he meets several new girls, though three of whom he gets to know the most out of anyone else. They are, the firm and obstinate Hayami Kohinata, the kind and obliging Hinata Kagura, and the cheerful and mysterious Otoha. As Takuma interacts with these girls, his medical condition gradually begins to heal.

An updated release titled H2O √ after and another Complete story Edition was released in 2009, containing the story content from both H2O ~Footprints in the Sand~ and √ after and another combined into one game.

Original H2O release contained: Hayami, Hinata and Otoha routes as well as their respective after stories (はやみの友達, 雪の振る道, 魔法少女マジカルひなた). Also a staff corner which includes 3 nonsense omake scenarios with nothing to do with the game at all.

Original Root after and another contained: Hayami and Hinata routes, with completely new after stories (Hayami: FOOTPRINTS IN THE SAND, 思い出の果てに, Hinata: レインボー). New routes are for Yui and Hamaji/Yukiji, which unlock the after stories 命の共有 and 夏草 (Maki's route). In the extras section there is a new after story for Otoha which includes blackjack and poker mini-games as well as H-scenes for multiple characters including Hamaji.
(For people interested, the Hamaji/Yukiji route is the one which is related to Sakura no Uta -Sakura no Mori no Ue o Mau-).
