This is a another random draft idea of a FanFiction I thought of after playing the Bedazzled Grail Concert! Crane Returns an Idol's Favor event in "Fate Grand Order" a few months ago in the spring of 2023. I thought about if the band girls and other crossover characters are in it, it would work well.

It's where the band girls from BanG Dream and other characters join Mash and Ritsuka in helping them in the Bedazzled! Grail Concert! Crane Returns an Idol's Favor event.

CiRCLE, Singularity...

The entire team was at the singularity's CiRCLE. The large group consisted of Ritsuka Fujimaru, Mash Kyrielight, X Alter, Miss Crane, the band girls including Hokage Tea Time, Class 1A, Barbara, Xinyan, the Valkyries Kiana, Mei, Bronya, Seele, Fu Hua, Theresa, and Himeko. Patrick, the Neptunias, Hatsune Miku, Shirou, Saber, Tohsaka, Sakura, and Illya.

Kasumi: So we get that this particle, Idol⭐️Glo can make idols strong enough to fight. But would that also affect us girls too?

X Alter: Exactly. It affects girls who want to be idols. Including their mothers.

Arisa: I can't imagine my grandmother being an idol.

Saaya: Nor can I imagine my mother being an idol too.

Patrick: Especially my mother.

Saber: I don't even wanna be an idol.

Shirou: The Holy Grail caused this singularity.

X Alter: So by winning over fans with unique charms, idols can get stronger.

Mash: That's why that girl we encountered was strong because she had loyal fans and wanted more fans to become stronger.

Neptune: So it works like Share Energy.

X Alter: I guess you could say that.

Miss Crane: Which is why we've started our agency, Chaldea Productions agency. 

Yukina: And who ever wins the competition wins the Holy Grail?

Miss Crane: Yes.

Marina: In that case. It's up to us to get more Idol⭐️Glo to get stronger so we can put an end to this singularity.

Kokoro: Sounds great!

Kasumi: With CiRCLE here we can be ourselves as always.

Aya: Now let's give it our all!

Everyone: YEAH!

And that was my idea. This is just a random idea I have and don't intend on making an actually FanFiction of this because it would take too long.
