My Take:

Summertime rendering is an anime that will keep you on the edge of your seat with its use of a time-loop narrative.

9. Link Click

Genre: Drama, Scifi

Episodes: 11

Release: 2021

Status: Upcoming Season 2

My Take:

Shiguang Dailiren, also known as Link Click, is a Chinese anime that takes viewers on an exciting time travel adventure. Cheng Xiaoshi and Lu Guang run a unique business in their small shop called "Time Photo Studio," They use their extraordinary powers to jump into photographs and help their clients relieve their regrets. But their job is not without risks, as they only have 12 hours and one chance to find what their clients are searching for without altering past events.

As the series progresses, it turns darker, becoming more of a psychological thriller than a straightforward adventure story. The twists and turns in the latter half of the series will keep viewers guessing, and the cliffhanger at the end of season one is both shocking and satisfying.

Despite its relatively short run time of 11 episodes, Shiguang Dailiren packs a lot of story and character development into each episode. The series also has an excellent English dub version, making it accessible to a wider audience.

Shiguang Dailiren, Link Click, is a refreshing take on the time travel genre. With its fresh anime style from a Chinese studio and engaging storyline, it is a true hidden gem of 2021.
