The credits for M-2.04 (Okawari ED) are different here and in the
single booklet, although the song is obviously the same. I'm not sure which of the two is correct, so I've left the single as it is.
Same for the chorus credit for M-2.05/06 (Okaeri OP/ED), here it's Uran while in the
single booklets it's hinako (which looked strange to me since that artist is credited as hinaco in other albums).
