User:Chukichi/Theories about the Akai, Sera, Haneda families

赤井務武's rich friend is the parent of Koji Haneda

Masumi Sera says that a rich friend of her father (務武) supports her. I think that the friend is the father or mother of Koji Haneda. If it is true, I can solve some questions.

Preconditions of this theory

• Shukichi Haneda is Akai family's middle brother.
• Shukichi is an adopted son of the parents of Koji.

Q1: Why did the Haneda family adopt Shukichi Sera?

Shukichi respected Koji, but I don't think that this is the reason.

The answer

Because 務武 and Mr./Mrs. Haneda were good friends.

Q2: Why does the friend support Masumi and Mary?

Even if the friend has a lot of money, I don't think that he/she spends a lot of money for a normal friend.

The answer

Because the friend's son-in-law, Shukichi, is the related-by-blood son of 務武.

The unknown child's real name is Mary Sera Akai

If this theory is true, one possibly is that the child's real name is Mary Sera Akai (赤井 メアリー世良 ,Akai MearīSera).
