Rinne - Sansara Naga (FC)
Rinne plays when the egg the player found under their deceased dragon's body hatches.
The song title comes from the Samsara Naga 1&2 Soundtracks album and is originally written in Japanese. The Japanese text 輪廻 means Reincarnation, or any related words. The title fits the game, as the hatchling introduces itself by the same name of the player's deceased dragon.
The song is in the key of C in the 4/4 time signature at a tempo of approximately 100 BPM.

The song was most likely arranged by Osamu Kasai, Masaaki Harada, and/or Shinji Nakayama, as ACC, the developer, is credited for programming in the game's manual, while Kawai is credited for music, and the three have credits in other ACC titles.
The composers wrote the music, most likely in 6502 assembly language in the second version of Advance Communication Company's Sound Routine sound driver. Because the game uses the second version of the sound driver, it is tuned approximately a ¼ step sharp.
