About the planner of this project
I love game commentators and streamers, and I'm a stogura observer who loves the emergency department box!
We are rooting for the characters and soul streamers, including Master Attendant Sorai, Momomi Obanai, and Tomo Akahage.
I often plan flower stands at events, and I also have experience in planning and implementing support advertisements once.
About the planning process and thoughts
We started this project because we wanted to celebrate Momomi-chan's birthday in a different way than before, and we wanted to convey our feelings of congratulations and gratitude. We thought there was something we could do to make use of our past achievements and experience, so we decided to create a support advertisement.
By making this project more than just one person, I think Momomi-chan will be able to express even more gratitude and support to all her beloved fans. I also hope that through this project and support advertisements, people who don't know her yet will have an opportunity to learn about Momomi Obanai.
This is my first support advertising project for an individual Vtuber, so there may be some imperfections, but I will do my best to make it a wonderful project!
Let's celebrate Momomi-chan's birthday grandly together! !
