Vacationed time: January 2nd - January 5th (three days). After probably spending a day denying it was worth her time and it's just a trap and she's above such nonsense. And then doing the exact opposite thing because that's how she rolls.
Vacationed place: Nerima, Tokyo, Japan
Brought with: Kuno's horrible Christmas "present," some of the pets she got in camp that she doesn't want to pay attention to anymore (i.e. all of them except Mr. Greenturtle II), probably just general crap she doesn't have any practical use for so it gets dumped on her brother.
Came back during: God, I dunno. I think post-manga canon.
Reason for vacation: Find fiancé, try to beat the crap out of him, then try to have sex with him. Browbeat elder brother, get family estate's defense systems in working order, get her plants and favored pets the care they need, track down rhythmic gymnastics team and bully them into vague competence. Maybe talk to Akane (maybe). See father.
What happened:
DAY ONE:
7:00 AM: arrive home, drop off things, check on Mr. Greenturtle I and give him breakfast, take in family estate for first time in three and a half years.
7:30 AM: Okay enough of that HEAD TO FURINKAN HIGH OR SOMETHING because maybe Ranma was held back due to missing a couple years or because he's book dumb or whatever.
8:00 AM: Arrive. Interrogate students. Temporarily knock out or paralyze ones who act stupid. Ransack class rooms. Probably get into a fight with Hinako that's closer than it would have been pre-camp but still doesn't work out well for Kodachi. Recover.
8:30 AM: Furinkan High proves useless. Up next, THE TENDO DOJO. Ranma isn't there either but it was worth a try. Either here or at Furinkan, run into Akane, who is uncomfortably nice and social. Probably some suggestion of getting together and talking is made by her which is not explicitly agreed to or rejected. She probably says something or other about Ranma not being around due to whatever reason (traveling the multiverse?). This theory is rejected, unspokenly, due to clearly being lies meant to keep Ranma from her. Clearly.
9:30 AM to 1:00 PM: Dammit dammit dammit where's Ranma
1:00 PM to 2:00 PM: Temper tantrum taken out on people who are inferior as martial artists and human beings; I.E. everyone.
2:00 PM to 4:00 PM: go home, take bath, feed tiger shark, sulk, wonder why she didn't just go to wherever Chizuru was or something
4:00 PM: Go out and find brother.
4:30 PM to 7 PM: Dumb sibling stuff. No bonding happens whatsoever, dammit. Empty, drained, punctured bottles of sparkling water are probably thrown at elder brother's head
7:00 PM to 10:00 PM: inspect traps and built-in weapons in Kuno estate. Fix whatever she can.
10:00 PM to 1:00 AM: Botany.
1:00 AM to 6:00 AM: Sleep. Too many things to be done for full night, that sleep can be made up in camp.
DAY TWO:
6:00 AM to 7:30 AM: Feed pets, drink protein shake or something. Track down entire St. Hebereke rhythmic gymnastics team. Drag them out of bed. Put the fear of god into every last one.
7:30 AM to 1:00 PM: Whip rhythmic gymnastics team into competence. (Probably not literally 100% of the time.) Assign interim captain. Find out the identities of the next team they're facing and the name of their star player.
1:00 PM to 2:00 PM: Find star player. Publically defeat and humiliate her in order to gain psychological advantage for St. Hebereke and possibly rid opponents of their best asset.
2:00 PM to 5:00 PM: Slapping people in the face with wads of bills just to remember what it felt like Shopping.
5:00 PM to 6:30 PM: Dumb sibling stuff.
6:30 PM to 12:00 AM: Botany and pet care and reclusiveness.
12:00 AM to 8:00 AM: Proper amount of sleep this time.
DAY THREE:
8:00 AM to 9:00 AM: Breakfast, feed pets, check on plants.
9:00 AM to 11:00 AM: Looooong bath.
11:00 AM to 1:00 PM: See father.
1:00 PM to 3:00 PM: Take scenic walk along rooftops.
3:00 PM to 4:00 PM: Actually interact with Akane on a vaguely less dismissive manner. Probably. I guess.
4:00 PM to 4:15 PM: ... slip into Ranma and Genma's room. Steal whatever remnants that prove that Ranma was there that she can.
4:30 PM to 6:30 PM: Dinner. Somewhat less dumb sibling stuff.
6:30 PM to 12:00 AM: Botany, take care of pets, check on defense systems. Go to bed, wake up in camp with bags she had packed before going to sleep.
Canon update?: There's no canon to update to, really.
Brought back: Things belonging to Ranma. Whatever they are. Sob. Also new clothes, new books, general stuff for new weaponry. Also, sparkling water. Take THAT, camp.
