School Days

The visual novel on which the series is based has 12 possible endings the player can get, with one in particular being the "worst ending" that can happen if the player is consistently unfaithful to several romantic partners, to the point that it results in murderous violence among several of the characters. The exceptionally dark second half of the series follows the events that lead up to this ending.

Makoto Ito is credited as a producer in the credits.
