In Another World, My Sister Stole My Name Keeps Piling on Suspicious Situations

In Another World, My Sister Stole My Name is an isekai shojo manga series that relies upon both love and betrayal. After all, Ichika ended up being something of a chosen one who could communicate with another world through a mirror, she told her sister Karen about it, her sister ended up disappearing there, and when Ichika does wind up spirited away she learns her sister stole her identity. There are some serious secrets and mysteries. Now with the second volume, even more are coming up and suspicious behavior is pretty rampant, but Ichika doesn’t seem to be catching on in the same way us readers likely are.

Editor’s Note: There will be spoilers for volume 1 and light spoilers for volume 2 of the In Another World, My Sister Stole My Name manga below.

As a quick reminder, the way mechanics worked in In Another World, My Sister Stole My Name means that there was a time difference between the magic mirror tying the worlds together. Ichika talked to a young prince named Cecil through it. When her sister Karen disappeared, she appeared in that kingdom, became grown-up Cecil’s fiance, and is a Saint due to possessing remarkable light magic. When Ichika came through the portal, she learned Karen claimed to be her and is going by “Ichika” there. She declared the real Ichika “Karen.” This means Ichika is now betrothed to the prince’s younger brother Noah, and he seems quite displeased about things. 

The end of the first volume of revealed plots are afoot. Someone targeted Ichika with a curse. Noah sensed it and got in the way. Ichika, as befitting the actual chosen one, used an incredible amount of light magic to save him and is now acknowledged as a second Saint.

This means that now so many suspicious and shady dealings are coming up in In Another World, My Sister Stole My Name, but I find it a bit frustrating that Ichika doesn’t seem to realize it. Noah is clearly hiding something, and as the volume goes on it is obvious he either knows or realized facts critical to Ichika and her situation. Since he’s her fiance and they spend an extended period of time together in these chapters, it’s a little frustrating that she’s not figuring out something is awry. I suppose you could use the excuse that she’s figuring out her magic powers and on her first Saint assignment, but still.

What’s going on with people around Ichika, Noah, and Cecil is equally obvious. Something is absolutely awry with Karen. It’s clear from the first volume. However, Ichika isn’t doing any sort of investigation. We see some of it begin to pop up here, now that they’re in close proximity and Ichika is a second Saint. But I’d have loved more awareness from our main heroine. Also, the only person who seems suspicious of the queen is Noah, even with some rather notable scenes in both volumes, and I’m surprised there isn’t more investigation into the curse directed at Ichika and Noah. 

The scenario Kotoko constructed is interesting for a reader. Because of the narrative decisions, we’re aware of all these webs, pitfalls, and machinations. However, I find it leaves me a little frustrated because I am seeing them, but Ichika isn’t. Instead, by the end of the volume, I get the impression she’s more upset by the fact that things are tense between Cecil and Karen, Karen and her, Noah and her, Noah and Cecil, and just… everyone. When really, I’m thinking, “Why aren’t you more concerned about your sister’s identity theft, the possible sabotage, and the attempted murder?”

To be honest, I’m still not sure how I feel about a series where the female lead is so clueless that she’s not able to see how suspicious everyone around her is acting. What’s keeping me reading the In Another World, My Sister Stole My Name manga is more of a desire to see everything blow up and admissions come out, rather than watch Ichika get her happy ending. Because it’s clear there are some revelations that Kotoko is incredibly close to sharing, but the author is just building a little more anticipation in the meantime. 

Volume 2 of In Another World, My Sister Stole My Name is available now, and Yen Press will release volume 3 of the manga on July 22, 2025.
