Kokokanon

Kokokanon is the femslash ship between Kokoro Tsurumaki and Kanon Matsubara from the BanG Dream! fandom.

Canon
Kokoro and Kanon are both in the band Hello, Happy World. Kokoro is the main vocalist and Kanon is the drummer. The two of them attend Hanasakigawa Girls' High School, with Kokoro being a second-year and Kanon being a third-year. The two have contrasting personalities, Kokoro is a very energetic and outgoing girl, whereas Kanon is more shy and reserved. Because of this, Kokoro tends to drag Kanon into all sorts of wild situations and gives her the push she needs to try new things.

Smiles To The World! Hello, Happy Union!
They first met in Hello Happy World's first band story, when Kanon was about to sell her drums because she didn't have the courage to play them. Kanon tells Kokoro that she lacks the skill to play the drums, so she can't even imagine playing in front of a crowd. Kokoro tells her that she can't decide whether she's skilled or not by herself, and that other people have to do it. But Kanon says she can't play because she lacks the courage to do so. Upon hearing this, Kokoro tells her with a smile that Kanon can take some of her courage. As the two start performing together on the street, Kokoro realizes how much fun it is and asks Kanon to form a band with her. Misaki, Hagumi and Kaoru would later come to join their band.

I Need You!
In Hello Happy World's second band story, Kanon waits near the school gate for Kokoro. Kokoro is upset because of the argument she had with Misaki earlier, and asks Kanon for advice. Kanon tells her that Kokoro is like a hero to her. She adds that the thing she loves about Kokoro is that being around her puts her in a positive and warm mood. Kanon suggests that she should try to give some positive energy to Misaki to cheer her up.

Niconiconnect!
In the third band story, Hello Happy World are invited by Kokoro's friend, King Nicolas, to perform at a festival in the kingdom of Happinelle. During their stay, they bump into Princess Nicolina, who looks exactly like Kanon. Kokoro says that Nicolina looks like the old Kanon; always anxious and  scrunching her face like she had a tummy ache . Kanon replies by saying the reason she was able to change was because of Kokoro and Hello, Happy World.

- Kanon to Kokoro in Hello Happy World's Band Story 2

"Kokoro-chan shines as brightly as the sun. Just being near her fills me with warmth and energy. I doubt I can be that kind of person, but... if I stay close, hand-in-hand... I can help share that warmth."

"I think I was only able to overcome my nerves because I had Kokoro-chan and Hello, Happy World."

- Kanon about Kokoro and Hello, Happy World

"I am a coward, and I don't have much confidence, I also used to think the world was full of things I could not handle. But the world changed once I met Kokoro-chan and the others. At first, it was scary because I kept getting pushed around. But then, so many fun and joyous things happened. I feel like I was slowly becoming the person I wanted to be."
