Project No.9 is producing the anime under the direction of Shinsuke Yanagi. The series scripts are overseen and written by Deko Akao. The characters are designed by Katsuyuki Sato.
The anime is based on a light novel written by Kyosuke Kamishiro and illustrated by Takayaki. A manga adaptation illustrated by Rei Kusakabe has been published on Niconico Seiga on May 2019 that still runs to date.
The light novel is being published in English by J-Novel Club. It describes the story as:
Ah, high school. Is there any better place to start fresh after a horrible middle school relationship? Nope! Not unless your ex ends up at the same school as you and is now your stepsibling. What was supposed to be a sanctuary of peace where I could avoid ever seeing her again has become a living nightmare! Everywhere I look, I see her—in my house, in my school, in my class. There’s no escape! She even claims that she’s the older sibling. Like hell she is!– J-Novel Club
But I won’t lose to her. After all, I’m the older brother in this new family situation. That’s right, we’re family now. No matter how much we may have thought we loved each other before, we saw one another’s true colors and realized we weren’t meant for each other. That’s why even though we may keep up a buddy-buddy sibling act for the sake of our parents, things will never go back to the way they used to be.
