April 2026
I really love Yunyun. Like, a lot. Like, a whole lot. You have no idea. I love her so much that it is inexplicable, and I'm ninety-nine percent sure that I have an unhealthy obsession. I will never get tired of listening that sweet, angelic voice of hers. It is my life goal to meet up with her in real life and just say hello to her. I fall asleep at night dreaming of her holding a personal concert for me, and then she would be sorry tired that she comes and cuddles up to me while we sleep together. If I could just hold her hand for a brief moment, I could die happy. If given the opportunity, I would lightly nibble on her ear just to hear what kind of sweet moans she would let out. Then, I would hug her while she clings to my body hoping that I would stop, but I only continue as she moans louder and louder. I would give up almost anything just for her to look in my general direction. No matter what I do, I am constantly thinking of her. When I wake up, she is the first thing on my mind. When I go to school, I can only focus on her. When I go home, I go on the computer so that I can listen to her beautiful voice. When I go to sleep, I dream of her and I living a happy life together. She is my pride, passion, and joy. If she were to call me "Onii-chan," I would probably get diabetes from her sweetness and die. I wish for nothing but her happiness. If it were for her, I would give my life without any second thoughts. Without her, my life would serve no purpose. I really love Yunyun.

Alright, this is work of art. It perfectly encapsulates a very distinct way of looking at the world, and the feeling that comes with it. Something that quietly reached a maximum intensity before the internet became mainstream. Qchan is our inner child. When we think of this concept of "inner child" we see some kid frolicking in the woods or eating ice cream at a theme park or something. But in reality we as children watched the world through the lens of social media. And all things considered, on a spiritual level, the world is just a bunch of crazy nonsense. In reality it is just a web of responsibilties trying to seep into our coccoon of safe solitude and fantasy. We have a feed of stuff that supposedly represents "things that are happening out there", but it's really just a screen with stuff on it.. And we're not even participating in any of it, it might as well not be real. We just sit there looking at a screen, alone. Having to take the world seriously is a weight on the soul, a weight that your inner child can not bear in principle. Just like Qchan is terrified of having to leave her bedroom. What a drag.. what an affront to civility. Why should I have to do anything remotely uncomfortable at all? Indeed! I should NOT have to. That's what I felt when playing this game, at least. It's so much more than just an homage to this aestetic. It carries within it the soul of it all. Now when the world is clearly run by idiots with their retardation on full public display we can't even pretend to be ok anymore, and this game is perfectly expressing my feeling. Or at least, how I think I should feel. ♥♥♥♥ it all... just make yourself safe and comfortable, enjoy yourself while it's all cooking out there, seriously. And I don't mean this in a nihilistic sense, but in a celebratory "you are free to do whatever you want" kind of way. I feel Qchan completely, she is spiritually correct and perfect

This is THE definitive rhythm game. The controls are smooth and responsive, the characters are great, the song choices are beyond comparison. I feel like someone followed my specific taste in music and humor and built an entire game dedicated to it. It's impossible to recommend this game any more than I do. I've never felt this seen by a project. Incredible price, incredible gameplay, incredible song choice. The difficulty is PERFECT. This is the Mona Lisa=--the Starry Night--no, the ♥♥♥♥♥♥♥ Sistine Chapel of rhythm games. Literally nothing comes closer to what I wanted in a game. I honestly wish I could be married so I could say this game's release date is more important than my wedding anniversery. God could come down from the heavens and offer me a billion dollars, but He'd take Yun Yun Denpa Syndrome away, and I'd tell em GET BENT, I'd rather live paycheck to paycheck. The only thing that would make this game any better is more Nanahira. I LOVE NANAHIRA.

Who is yunyun? For the lost, She is the vision. For the hungry, She is the chef. For the thirsty, She is water. If Yunyun thinks, I agree. If Yunyun SENDS, I RECEIVE If Yunyun has a million fans, I am one of them. If Yunyun has ten fans, I am one of them. If Yunyun has only one fan, that is me. If Yunyun has no fans, I no longer exist on this earth. If the whole world is against Yunyun, I am against the whole world. Until the last single bit of denpa received, i will, love Yunyun.
