I think Seiran is there to show us how a pure being like Lunarian would feel if they fall into hell, a place full of death. Also to make connection between Enoko's jewel and the Lunar jewel because both has similiar purifying properties.
Then again this isn't the first time a character become playable without adding much to the plot, like Meiling in Hisoutensoku. ZUN just like showing minor details like that, even if he has to go all the way to make someone playable or write an entire manga chapter for it.
