Hello fellow readers, and happy May! It’s another month, which means we’ve got ourselves another excellent batch of new manga releases to get excited about! On a completely personal note, I am particularly excited about this month because I’m on vacation for the first time in about four years (GAH!). But no matter what this month means for you — maybe you’ve made it to the home stretch and are wrapping up the school year, maybe you’re looking for a way to spend that extra pocket change you got from your tax return, or maybe it’s just another typical month — the perfect companion is and always will be a nice stack of books. And, as always, I’m here to help you find some manga to add to that stack!
This month, we’ve got an amazing selection of new manga to choose from (not that this isn’t the case always, but anywho). Get ready for a fake dating high school romance between a girl who just wants to fit in and a boy with a seemingly harsh personality, a dystopian thriller about a young girl trying to rescue her long-lost brother, a comedy about a yakuza member turned K-pop mega-fan, and more! This month is particularly great for animal lovers too, with a sweet and heartfelt story of the bonds between cats and humans, and not just one, but two fun slice-of-life manga about adorable Shiba Inu antics. So what are we waiting for, let’s dive in!
