ONIMAI: I'm Now Your Sister!
Mahiro Oyama was just a normal erotic-game-loving dude... until he woke up one morning as a woman! Turns out his mad scientist little sister, Mihari, tried out one of her new experiments on him...with a disastrous outcome, as far as Mahiro's concerned! But Mihari is as determined to study him as he is determined to go back to his shut-in, game-playing life, and one thing's for sure...life is going to get a whole lot weirder from here on out!

Read Free
We allow users to preview titles in our library by making the first chapter — or even beyond, for selected titles — available for free. Through free previews, you can get a feel of not only what a title is like, but also whether Manga Planet’s line-up is for you.
Read with Points
The individual-purchase model is recommended for users looking only for specific titles. For a reasonable price, you can digitally rent chapters or volumes for a specific period of time, or digitally purchase to access them for an unrestricted period of time.
Read with the Manga Planet Pass
The Manga Planet Pass is a cost-effective, value-added way to enjoy our diverse catalog of titles. Choose from five plans according to your budget and lifestyle: 1 Week, 1 Month, 3 Months, 6 Months, and 12 Months. For a fixed fee for your chosen duration, you can read as many titles (that are covered by the Pass) as you like within the Pass’s validity period.
