Handyman Saitou in Another World (便利屋斎藤さん、異世界に行く, Benriya Saitō-san, Isekai ni Iku) is a Japanese manga series written and illustrated by Kazutomo Ichitomo.

It has been serialized online via Kadokawa Shoten's ComicWalker website since October 2018 and has been collected in twelve tankōbon volumes.

Dejected over getting unfairly fired, he accidentally walked in front of a speeding truck and was subsequently displaced into a fantasy world, where he was taken in by an adventuring party.

With the party members' personal quirks hindering their performance, Saitou begins lending them a helping hand, carrying essentials, picking locks and giving them vital reminders, thus making him indispensable to his new friends.
