Cal Gaiden: Tiny Steps

Cal Gaiden is not directly connected to other Cal games story-wise, completely abandoning the protagonist Wataru Ishibashi, the storyline concerning ancient Greek gods, and the multi-cultural fantasy setting. Instead, it follows the exploits of Satoru, a young man who its trying to find the love of his life. There are four possible candidates: the initial romantic interest Mari Inoue, the elusive Manako Sakamoto, and two co-workers - Ami and Yōko.
