Let's summarize this. In Japan:
Adultery is not
Common-law marriage is
But there is
a catch: Common-law marriage is only valid under several conditions which vary from one place to another (in some jurisdictions, a couple must have cohabited and held themselves out to the world as husband and wife for a significant period of time). Under Japanese jurisprudence in particular, the couple has to actually live together. That must be one of the reasons why Mion, Rena and Satoko keep their relationship with Keiichi as discreet as possible even now (probably each of them also avoided co-ownership or co-tenancy of property with Keiichi alone and their children were legally registered as fatherless).
In other topics:
I was thinking if it's feasible for SOS Brigade to invite "teachers" to their daily trainings. Nagato must be capable of figuring out on her own almost any topic for them to learn, but how about highly specific subjects that are not so easily available or when they are heavily dependent on personal experience. I will be honest, I was thinking in Shinobu
teaching ninjutsu to Tsuruya (final results may vary from picture
) and Yuuto teaching his driving skills
to Kyon. If the brigade need to preserve secrecy from them in the future (for some reason I believe that Shinobu and Yuuto are going to get involved more deeply with the brigade) Nagato can delete all their memories from the event if she has to (like in the movie Paycheck
IMO, it's very likely Miyuki take notice of Keiichi, even if it's only his name what appear in court. Her mother told her a lot of stories about her father and the IDSE can "help" her to make that connection. About Miyuki, she must be about 32 or 33 years old in K:BDH (she born in 1978 *
) and she uses her maiden name "Akasaka". IIRC, Miyuki was married in the visual novels *
(her last name was Sorimachi) so she must be divorced or she never was married
in this timeline.
One last thing. I was thinking about Haruhi's new power upgrades and if this is going to the cue for Nonoko's Magical Girl
upgrade. I don't actually picture Nonoko as a Magical Girl Warrior
(Kyon wouldn't allow it if he can avoid it) but how about a some kind of non-lethal Upgrade Artifact
to start? She had already proved to be very capable for her age, supporting of Kyon's cause and very Genre Savvy
about his adventures (Wrong Genre Savvy
to be exact, but she has a surprising good grasp of the situation in her own terms
). I think something to improve "her own brand of little-sister espionage" and to facilitate her and her family defense in a emergency would be ideal.
