Aegean Kai No Shizuku

Aegean Kai No Shizuku (エーゲ海の雫) is a Adventure/Point-and-Click/Puzzle video game published by Illusion Core and developed by Illusion Core released on December 15th, 1995 for the PC-98.

You play as Triton and explore various realms to hunt down four swords. Although there are plenty of strange and unique characters to encounter, the narrative is relatively slim, which is a huge departure from typical Japanese adventure games; meanwhile, the puzzles are easier than the mindbenders typically found Myst-style point-and-clicks.
