"And so, starting that day, the two of us, Hayafuji Kasane, and Aoyama Meguru, began our new life together as contract sisters."
— Hayafuji Kasane
Contract Sisters' (ケイヤクシマイ, Keiyaku Shimai) is a Yuri manga by HIJIKI that began serialization in monthly magazine Comic Cune in 2022 and is currently ongoing.
On the surface, Hayafuji Kasane is a aloof and beautiful Office Lady. In reality, she is a Closet Otaku who hates her job. Kasane finds herself drawn to Aoyama Meguru, a high schooler who works in a family restaurant. Through a series of mishaps, Kasane and Meguru sign a contract and move in together, becoming “Contract Sisters”. The first chapter has been adapted to a voice comic by Kadokawa, which can be viewed here.
Contract Sisters provides examples of:
- Bifauxnen: Kasane’s friend from high school, Mii-chan has become one in the present.
- Beneath the Mask: Under her cool and formal exterior, Kasane is a bumbling and slightly awkward otaku.
- Cool Big Sis: This is what the “Sisterhood Contract” makes Kasane to Meguru, even if Kasane’s feelings secretly aren’t sisterly. Meguru’s real elder sister is/was one to Meguru as well.
- Closet Otaku: In the first chapter, Kasane is depressed that her favorite Idol Singer graduated and that a Yuri manga she liked was cancelled.
- Last-Name Basis: Kasane refers to Meguru as Aoyama-san until she is told not to.
