comicGAGA is shounen-oriented magazine. If there's any shoujo-ai/GL series in it, don't remove the shounen tag.

Tokyo Mangasha owns active BL magazines:

Discontinued BL magazines:

• MARBLE (Vol. 1-4)
• BGM
• CuCue
• Catalogue Series (this magazine is divided into many names but is combined)

If you want to see the serialization publication date, you can look at the table of contents of the tankobon release. Tokyo Mangasha does this for their BL titles. Please make sure where it's being serialized and what year. Don't put print labels if magazine for serialization exists.

Marble (i.e., Marble Comics) is an imprint for their tankobon releases, not a magazine. Please don't put it under "Serialized in (Magazine)"
