I don't do Manga or FF, but there are common aspects to real books
you have 3 things there that are' as Shipped', not how they should be indexed by Calibre.
I split them into their
proper places.
Later, Templates will mumble them into the form needed by a particular reading device
Attack on Titan {series}
Volume 1 {series_index} (dropping the unneeded word 'Volume')
Prototype {title}
The only time I leave "Version, Volume, Issue" (or abbreviations) in the{ Title} is when there is no Unique title otherwise. I always remove Series if there IS a Title. I also drop subtitles (variations can make them unreliable for detecting duplicates)
my 2 cents
Orbit 5 {title} (you can't remove the volume # and be unique)
Orbit {series}
5 {series_index}
ABSOLUTLY use the plugboard
