Hiroki Kikuta is a self taught music composer who wrote the music for Secret of Mana 1 and 2, also known as Seiken Densetsu 2 and Seiken Densetsu 3. According to an interview, he was hired by Nobuo Uematsu, and had only two weeks to write all of the music in Seiken Densetsu 2! I think he was given more time to write for Seiken Densetsu 3 because that game's music is more varied. For example, SD2 has 50 themes in all, 3 of which are for bosses. SD3 has 69 themes, 11 of which are for bosses.

After SD3, the Seiken Densets team left Squaresoft and broke up to form Brownie Brown with the programmers and artists, and Hiroki Kikuta on his own. With the help of SNK he formed Sacnoth and was in charge of Koudelka and Shadow Hearts.
