Whilst you wait for the IFM vocal in the mid-230s range, why not try Reisen's stage theme, Kagome-Kagome? This came from Seventh-Heaven Maxion's C76 album by the way, it consists of different arrangers and performers from different circles, namely Silver Forest, Innocent Key and SYNC.ART'S (FFFF YEAH) and two other circles participating this album are R.CYBERBARD and Reliance:Tone. This Kagome-Kagome vocal has gained R.CYBERBARD their place in this playlist; a fantastic job in arranging such a great Imperishable Night BGM.

I've only seen non-vocal arranges of Kagome-Kagome, my favorite one is xi-on's and this would be a great addition in the existing Kagome-Kagome arranges.
