Rikka has everything a woman should have:
competence (intelligence, practicality, diligence)
health (youth, fertility, beauty)
parental skills (compassionate, supportive, devoted)
She's cold and indifferent towards the MC at first, so you have to "conquer" her, but also needs you to "save" her. And I'm a sucker for that kind of thing.
She has a good balance of seriousness and playfulness and her dere levels are off the charts.
AND she's a masochistic buttslut.
What more could you ask for?
