## Description
_Uch ū Tantei Divan_ is a follow-up to Jantei Monogatari, though it can be
hardly considered a true sequel because of its entirely new setting and
themes. Set in a sci-fi environment, the game casts the player in the role of
Divan, a young man who possesses the ability to transform into a powerful
supernatural being, and is entrusted by military authorities to protect Earth
against an alien demonic attack. This can be done only by defeating the evil
minions in mahjong games.
Though featuring elements of a Japanese-style adventure game (verb commands
that must be selected from a menu to trigger the next scene), the game focuses
on mahjong matches against opponents, which occur as dictated by the plot. The
game uses standard mahjong rules, with the exception of bonus powers that can
be acquired for points distributed after each round and used in subsequent
matches.
