7:33 My Kami Oshi just can't stop taking Ws you love to see it Congratulations on your 1st Official Anime Opening Calli ❤☠❤

Congrats Calli, its always so amazing to watch you reach your dreams. Your an inspiration to all of us and we are so proud of you. You're literally opening up the world for all VTubers with all your achievements. I want to see you reach even higher dreams you have !

Seeing Calli as happy as she is about the OP has made me incredibly thankful I decided to follow her journey five(!) years ago. I will forever cherish being able to call her my oshi.

Congratulations! So happy to be part of this journey with you. Huge W!

Congratulations Mori! I’ve been really enjoying watching Gachiakuta and I’m so glad you’ll be part of it. It’s such peak anime. One of the best of 2025! I had wishful thinking that your voice would perfect for this anime for a season 2 opening - only for you to reveal you’re the artist for the second opening of season 1! Even better news!!! It’s gonna be a banger!

I’m beginning to think this Mori calliope person is pretty swell. Jokes aside, big congrats to you! This has gotta be surreal but as I’m sure everyone here can attest to, it’s well earned. Get yourself a bit of rest, then it’s right back into the ring with you.

I couldn’t be happier for you, Calli! What an amazing accomplishment this is, it’s been such a trip watching you and all of EN grow these five years. Let’s get even more anime OPs! ❤

Congrats Calli I knew the moment they announced the Gachiakuta anime that you'd be involved and have been watching the show in anticipation

Congratulations on the awesome announcement, Calli. I've never heard of Gachiakuta (art looks cool), but the fantasy of getting to sing an Anime OP for your favorite Manga/Anime is something I dreamed of as a teen. It's beautiful to watch it happen live in front of your eyes. I remember watching the credits of DC's Squad Anime, and having my mind blown when I saw it was you behind the song. I hope your talents start catching up to people around the world. Your hard work is inspiring to me, us, and everyone who supports you.

Really, even if the signs were there, to see you being announced as singing the opening for Gachiakuta, it’s still settling in on how huge this achievement is.your debut goal, successfully reached!I love Gachiakuta so much, and it really is all thanks to youyou’re our inspiration that even the dreams we thought impossible can still be achieved, we’re so, so proud of you, Calli. THATS OUR KAMIOSHI!! \/

We're watching dreams come to life in real time. I'm so happy for you Calli!!

I am so happy for you Calli. You deserve this success. My IRL Dad is literally the only person I know who used to work as hard as you when he was younger

hell yeah cali, been loving this series and been loving you! super cool to working on such a dope project

WE'RE SO PROUD OF YOU, CALLI

Congrats Calli! I'm really looking forward to hear your first anime op!

The brave Reaper girl is so cute being shy😊
