I am convinced it's Fuu-chan. I am also convinced that her real name is Futaba. Now, what about that name? The thing is, I think that the four big names have a very big connection with "
The Four Sins That Cry to Heaven for Vengeance" or "
peccata clamantia" - "
Sodomy", "
Willful Murder", "
Oppression of the Poor, Widows, and Orphans" and "
Defrauding Laborers of Their Wages".
Now you might be asking: "What do these sins have in common with the names?" and Well... Let's take a look at what everybody was doing: Yotsuba, Yotsuha's mother, enticed a married man into having an affair with her and blackmailed him until he committed suicide purely for entertainment. That engraves "
The Sin of Sodom" onto her name - She commited an act of Sexual Perversion and paid for that by being murdered by Yotsuha's brother. By killing his own mother, however, Yotsuha's big bro commited different sin "
Willful Murder" or "
The Blood of Abel". I bet he will be the next one to perish in the hands of Futaba. Now, Futaba is angry, wants vengeance, but her main target slipped away because of the homicide commited by the brother and now she has unfilled revenge. What does she do? She starts to target the person who is the closest to an actual, viable target (Yotsuha) BUT, by doing that, she commits the third of the four sins "
Oppression of the Poor, Widows, and Orphans", because both Uichi and Yotsuha fall under the category of "
The Poor, Widows and Orphans". (Uichi's family struggles financially, while Yotsuha is orphaned.). She starts to manipulate things behind the scenes, making bullies target her first love, Uichi, yada yada...All in order to make Yotsuha's life miserable. But wait! Yotsuha's gained time travel abilities. And so, she goes on to confront whoever is making her Uichi die every single time, even resorting to extreme schemes and self-defence...Completely unaware she is committing the last of the four sins, "
Defrauding Laborers of Their Wages". In short, she is taking lives. You would think that's bad BUUUT WAIT A MINUTE! WAIT!!! There is something to be said about that by St. Thomas Aquinas. In his theological book, "
Summa Theologiae", he says:
"If the need be so manifest and urgent... then it is lawful for a man to succor his own need by means of another's property, by taking it either openly or secretly: nor is this properly speaking theft or robbery."
and Yotsuha is doing exactly that. She is taking the lives of the people who make Uichi's life miserable and is actively trying to help him. She does something that is known as the "Robin Hood" effect.
What I predict is, the big bro, one way or another, will die, and then, after that, Futaba will reveal herself and confront both Yotsuha and Uichi and either:
A. She gets herself killed in a case of self-defence.
B. She gets herself killed by someone she is manipulating.
Or
C. She kills herself.
No in-betweens.
But then it's only a theory and we might need to wait and see.
