yea moved the entire thing by -9. Everything sounded a bit off (I think) after you mentioned that

It's kinda exaggerated to put the whole band as an artist while there are only 2 people featured in this song which is Hoshino Ichika and Hatsune Miku and also DECO*27 should be the one in the artist field as well. By right you're missing the Japanese HIBANA " ヒバナ " as well as the artist field and romanized artist field inconsistent spacing.
Should be
Song title: "ヒバナ -Reloaded- feat. 星乃一歌 × 初音ミク"
Romanized: "HIBANA -Reloaded- feat. Hoshino Ichika x Hatsune Miku"
Artist: DECO*27
Tag
could add " ニーナ niina video game leo/need l/n japanese jrock j-rock 野口 瑠璃子 heyimjarvis "
also remove the (CV: ) in the tag as well
mind to explain the " mes " in the tag field ? otherwise please remove it
The song is produced by DECO27 while they just sing another cover. and also look at the description there stated " 作曲：DECO27 ". Whoever sings does not matter in the artist field there are many different covers but in the end, it's still a DECO*27 song.
Yes, I agree the group Leo/need involved but there's only Hoshino in the music. Based on the official game https://www.youtube.com/watch?v=X-V08K-TIXA&t=7s there stated Hoshino Ichika and Hatsune Miku. It wouldn't make sense like dragging the whole team while it's just one of the members performing the entire time.
Cover artists or primary singers are typically listed as the artists on osu (search utaite or vtuber to see this very many times)
Saying feat would imply they did this as the original version with deco which would be misleading as it's only a cover
As linked already specifies it as the group rather than just ichika which the map already follows.

Leo need is considered the album artist as well which this cover is featured on
Leaving the title unchanged ( additionally, also follows a recently ranked mania set of this which uses similar metadata to mine https://osu.ppy.sh/beatmapsets/1793916#mania/3676608 )
Added some missing tags. Removed "mes" (forgot why I put that there)
