Kagiri Araido is a Japanese manga artist known for creating wholesome and fantastical slice-of-life stories, with the most prominent work being the series Grandpa and Grandma Turn Young Again, known in Japanese as Jiisan Baasan Wakagaeru. The artist's name in Japanese is written as 新挑限. Araido is primarily recognized as the original creator and author of these manga works, serving as both writer and illustrator.

Araido's most significant commercial and critical success is Grandpa and Grandma Turn Young Again. The series began as a web manga, first posted on the artist's Twitter and Pixiv accounts on October 26, 2019. The story follows an elderly farming couple, Shōzō and Ine Saitō, who wake up one day to find their bodies have reverted to their twenties, leading to heartwarming and comedic situations as they navigate their renewed youth while retaining their decades of shared memories and elderly sensibilities. Due to its popularity online, where it garnered over one hundred million views, the series was picked up for professional print serialization. It ran in Media Factory's Monthly Comic Alunna magazine beginning on July 13, 2022, and was compiled into eight tankōbon volumes by Kadokawa. The series was a commercial hit, with one million copies in circulation as of October 2022, and it was ranked sixth in the web manga category of the sixth Tsugi ni Kuru Manga Taishō in 2020.

The success of the manga led to a television anime adaptation. The anime series, produced by studio Gekkō, premiered on April 7, 2024. For the production, Kagiri Araido is officially credited as the original creator and for the original character designs. The series was directed by Masayoshi Nishida, with scripts by Yukie Sugawara. The anime adaptation brought the story of the rejuvenated Saitō couple to a wider audience, solidifying Araido's place in the industry as a creator of a successful multimedia franchise.

Beyond this flagship title, Araido has worked on other manga series. In August 2023, Araido launched a new series titled Undertaker in Kodansha's Monthly Shonen Magazine. This work marks a notable departure from the lighthearted domestic comedy of Grandpa and Grandma Turn Young Again. Undertaker is an action-oriented story centered on agents who battle resurrected undead creatures known as Sotai. The series concluded in July 2024 and was compiled into three final volumes. This demonstrates Araido's range as a creator, showing an ability to handle both gentle romantic comedies and darker supernatural action narratives.

Kagiri Araido's career trajectory is characteristic of a successful digital-age manga artist, having transitioned from independent web posting on social media to professional serialization and eventual anime adaptation. The artist's body of work, while still growing, is marked by strong visual storytelling and an ability to connect with audiences through both heartwarming premises and more intense genre fiction.
