Because composers and singers are great. For example, composers such as Suigetsu Ryōmae, Jun Higuchi Hideki Tororo, and other composers have made great songs. Recently, there are many other composers and some old composers. They are all very good composers, and there are also some labels that help GAL compose music, such as Solfa, Angel Note, etc. Their own reliable ability has also written many good songs for Gal, and they have basically been there since the last century. There are many similar labels, such as DOORS ENTERTAINMENT, etc. As for singers, there are three former doujin singers (Katagiri Agiri, Shigezuki Haruka, Chata). These three basically often sing OP/ED for gals. , others include Duca (named Mao in the world), Rita, Miyuki Hashimoto, Nao, KOTOKO, and others who not only dub GAL but also sing OP/ED for GAL, just like in the world The OP/ED singers in dramas are often voice actors, and the GAL world is actually similar, such as Aoba Apple Sakakihara Yuu, etc. There are many others that I won’t introduce one by one... In addition to dubbing, these CVs also include singing skills. Of course it’s not bad, so because there are many powerful individual composers and composing labels and companies, as well as talented singers, CVs, etc., when the two are put together, there will naturally be many great GALs.
