It’s been a long time since Hatsune Miku’s debut in 2007, and countless masterpieces have continued to be born.

preemptive refutationparipari sara udon

It’s an ambitious work that looks to the future while quoting famous sayings from across time and cultures with a touch of irony.
Released in February 2025 by Paripari Sarau-don, the piece unfolds as a back-and-forth between Otomachi Una and Kasane Teto.
The troubles we face today can all be solved by the words of past philosophers and great figures… That phenomenon is expressed by the title “置き論破” (Oki-Ronpa, roughly “pre-placed debunking”).
Yet from there, the song’s development conveys a resolve—“I’ll live believing in my own strength”—that you can’t help but empathize with.
It’s a pop song that gives you the energy to face tomorrow.
The wolf fell in love with Little Red Riding HoodHitoshizuku P

The song progresses from both perspectives: the Wolf (Kagamine Len) and Little Red Riding Hood (Kagamine Rin).
If these two were to meet, the story’s ending would be… so they intentionally avoid each other.
It carries a slightly bittersweet feeling.
If sung by two women, the key might fit better.
Warm and cozy in the bathfuwari P

It’s a cute, heartwarming song that makes you feel all warm and cozy as you listen.
It was originally supposed to be unlisted, but the Vocaloid producer accidentally made it public, and without that, it probably wouldn’t be as well-known as it is now.
Also, a masculine voice comes in partway through, making it sound like a father and his young daughter singing together while taking a bath, so it’s perfect for Father’s Day.
The dancing cat saysmarashii

The lyrics have a stylish feel, like a Western castle.
They’re snappy yet endlessly adorable, and the unique wordplay of weaving “nyan” into key words is charming as well.
It’s not a very famous song, but its cuteness is exactly the kind that deserves much more recognition.
Oh, glorious early summermowamowa P

It’s a refreshing waltz-style song, but… It’s a piece by Mowamowa-P, known for tracks like “Pollen Season,” released in 2009.
The extremely straightforward lyrics sparked a lot of discussion.
Describing those lyrics here is difficult for several reasons, so please take a look for yourself.
I’d like to live this honestly, too… That said, the tune itself is truly pleasant and will put you in a relaxed mood.
Perfect for a sunny day in May.
