The February issue of Futabasha's Comic High magazine announced on Wednesday that Tsutomu Mutsuki will end the Is This Girl For Real?! (Kono Onee-san wa Fiction desu!?) manga in the next issue on February 21. The manga's seventh volume had announced earlier this month that the series will end in the next volume.

Mutsuki (Ikinari Neko Kick, Momoiro Peanuts) launched the series in Futabasha's Comic Sumomo magazine in 2010, but it moved to the publisher's Comic High magazine in 2012. Crunchyroll began releasing the series online in English in January 2014.

Crunchyroll describes the story:

Jun Yoshikawa is a boy with a manga artist for a mom. One night, he gets in a situation with a drunk stranger, Narumi Kawase, and decides to look after her. She becomes a live-in assistant at the Yoshikawa household as Jun takes care of her. This is an age-gap comedy about a pre-thirties, unfortunate beauty with no skills nor a job, and a perfect high schooler who helps out his mom and does the household chores as they live together.
