This is a story by the author of Kero Kero Chime, and you can tell. The characters look similar, though the plot seems different.

Rupika lives on a far off planet called Rakariina and has a growth on her head that looks like a tiara (called the Twinkle Tiara). Her grandfather tells her that her destiny begins when she meets a man with the Twinkle Crown. Every so often on this planet, a lot of meteors fall and a lot of new aliens land on the planet. Rupika goes out to see this and maybe find 'her prince' (the Twinkle Crown) and is captured by a boy named Alpha, who then mentions something about someone named Rozeus. Rupika wants to see Rozeus and leaves Alpha's spaceship, which is actually a big turtle. The new aliens seem to know something about her tiara and start harassing her, and though Alpha tries to control them he gets knocked out. Rupika's situation turns desperate but suddenly a man with the Twinkle Crown appears.

From The Pink Panzer:

In the year 2999, only eleven cities still survive on Earth. The climate has changed drastically, and a biochemical apocalypse has made women extinct. For centuries, the male population of Earth has survived by depending on only one woman, called the Holy Mother, whose ova are harvested to create genetically engineered children. By now, any concept of a world in which women exist as ordinary people is long gone. Society has re-structured itself around all-male families, and relationships between men and adolescent boys have become the norm.

At the beginning of Marginal, the Holy Mother is assassinated by a terrorist known as Grinja. The government in power doesn't want to start a mass panic, so it pretends that the Holy Mother has only shed her vessel, and that she will be miraculously "reborn" in the near future. The public, which is superstitious and devout, believes this easily. Only government officials know that behind the scenes, there is a frantic effort to create a being able to give birth.

The manga's story revolves around Kira, who becomes involved in a three-way relationship with Grinja, the aforementioned terrorist, and Ashijin, a young man who calls himself Kira's owner. A complex plot and flawless world-building make the story irresistible, and Kira's search for freedom is as symbolic as it is gripping.

One day, a young man is found unconscious outside the shared-household where Ayato lives. Despite the warnings of one of his housemates, Ayato lets the person live with them temporarily. It turns out that the young man is Ryou, who used to be Ayato’s childhood friend back when he was two years old. Both of them had previously been separated since eleven years ago, but are now reunited.

Ayato, filled with happiness as he reminisces about their early memories, is gradually drawn to Ryou. However, Ryou appears to be glum with melancholy, as if he's hiding something important…?!

From Yaoi Is Life:

One day, I wondered about people's anal sex fantasies. Attempting to inject as much realism to a fantasy as possible, I decided to make the main character of this story a sex service addict. But he works at a book store? The more I think about it, the more complicated it gets. Would that even make an entertaining story? Can the seme make up for the useless uke? ...That’s what I thought as I drew this. There are many kinks I sadly was unable to include in this story. When I got the first version back, I realized that because of the corrections, everything around the genitalia disappeared… But what upset me most was how all the pubic hair vanished!
