Here’s a list of the stuff I tend to link from time to time. They’re not perfect and vary on how underrated they are but all of them managed to stay with me in one way or another so that’s something.

• Sui and Neri of the Twilight Planet - a cute (and short) slice of life series about a girl and a talking sloth running an inn on a dying Earth. Art reminds me of Girls’ Last Tour (also read that if haven’t and want some post-post-post apocalyptic adventures).
• Satellite Coin Laundry - sci-fi comedy about a space laundromat. It has some great panels as well as interesting aliens and ideas. Translation doesn’t update particularly often unfortunately.
• Traveling Gyaru - fun travel story about a gyaru who decided to bike through a good chunk of Japan for her friend’s wedding while knowing nothing about traveling on a bike. Nice art, interesting trivia about traveling and locations but not fully translated (last mangadex updated was over 2 years ago).
• I also like your flaws - an awkward boy and an amputee girl meet during their first day at school, start hanging out. It’s a oneshot and could use a serialization to expand on the characters but it’s a neat read.
• Pen Pal at the End of the World - another oneshot, this time about a young girl and a former artist exchanging letters in a post-apocalyptic setting.
• The Boy Who Collects The Stars - a short, magical story about a search for a mythical six-legged deer.
• The Unwomanly Face of War - World War II stories from a perspective of women who served in the soviet army. A unique look at a “overplayed” topic. Based on a book with the same title.
• Kowloon Generic Romance - romance, drama, sci-fi? It’s a slow burn series about life in modern day Kowloon. It has both goofy and striking panels, some a bit more risque but don’t expect a lot of fan service. It also has an official English release.

Finally, read Girls’ Last Tour everyone. It’s good. Read it.
