Oh man Kuro no Ken (Black Blade) was such a fun game. Fun fact: a friend tried translating it a long time ago but gave up only about 2 months in. Still a hell of a fun game though. The 3/4 back view for the battle system really hits home as I am a huge fan of it in the Shining Force and Golden Sun games.
Bless this thread.
Blade of Darkness is a better translation of the title.
Also one of Forest's only non-eroge.
