In this final post we shall cover the leftovers.
Putting aside her second brother and the mysterious girl, Sera Masumi also has her fair share of some unresolved mysteries.
So who is this mysterious girl that lives with Masumi at the hotel?
Ever since Sera Masumi was introduced in the manga a few years ago, more and more mysteries and questions regarding Akai Shūichi’s family have surfaced, to the point that the situation around said family has become fairly convoluted and a bit difficult for some readers to follow.
In a series of posts, we’ll explain the various mysteries surrounding the Akai family, summarize what we know, and talk about the popular theories regarding these mysteries.
We won’t be spoiling any cases, but just refer to the relevant information regarding each mystery.
If you are not up to date with the manga and do not wish to be spoiled, do not enter this post.
Disclaimer: The theories that will be featured in these posts are currently the most popular theories in the fandom regarding these mysteries. These are not guaranteed to be 100% correct when the mysteries are resolved in the manga. Moreover just because these theories are popular doesn’t mean you have to subscribe to them.
The first mystery we shall tackle: Sera Masumi’s second brother.
