I mixed those two songs together because I thought the instrumental parts at 3:10 felt like the same. Whenever I listened to that Phantasm song, the instrumental part would remind me of the Stratiotes doujin song, so I came up with the idea of mixing those two together at the right moment.

I do not own any right on those songs, they belong to their respective owner.

Harukanaru Idei Yona is a track composed by Phantasm and part of the single titled Haritsuke no Misa.
White Lotus (Part 2) is a track from the doujin album titled Amorphous, and arranged by Mr. Sweden, sole member of the doujin titled Stratiotes.
