Theory: New character Sera Masumi Is An FBI Agent

[MadelineLime]

We don't know Sera's real age, she could be lying about it all.

well... even if she is younger it would still be creepy.... if she is older... even more so

but i just remembered that akemi and akai just met for the first time approxamately 5 years before the storyline(canon isn't it? ) ....

There's too many unanswered question who is Masumi Sera really is. 

One thing I'm sure though, she has great deal of interest in Conan. 

Somehow, she knows who he really is.

Or maybe she know Ai's sister well, and last time she saw her is few years ago. If she's here for Akai's search, she will wonder what really happen. probably all along Sera's story is simple. She could be Kudo Shinichi's fan and haven't heard from him since his 'disappearance', confused or trick Eisuke to confess the secret he hold, and learn Conan and FBI involve with her brother's death.

If Akai's mission is to protect Haibara, (it's a bit like a movie of 'Terminator', the reason is the disk Conan once stolen is about immortality and 'resurrection', I see many metaphors is a bit like story of Terminator.) I'm convince to think Sera looking for good allegiance.

Sera Has a Possible Connection to "Deceased" FBI Agent Akai Shuuichi

In File 771, when scolded for his actions in the previous case by Haibara, Conan says that Sera is "not an enemy" because she resembles someone he met before (pg 11). Conan has previously worked with Akai during the Clash of the Red and Black. Sera physically resembles Akai (compare the two faces, especially the eyes) who is also a Japanese-American. Also, as some people have mentioned, the name "Sera Masumi" is very similar to the name "Sayla Mass" (Seira Masu), who is Char Aznable's younger sister in the Gundam Wing anime franchise (Akai is named after Char Aznable himself). Also, Sera mentioned that she moved to America three years before the current timeline; this was around the same time when Akai infiltrated the Black Organization as "Morobashi Dai".

That's interesting. I like this theory.
Gosho does like taking another anime's character name secretly.
