Ahh Kaoru-chan, if I could show you around Otsu, I would! Everyone there is really friendly and welcoming. They're all looking out for each other and for my brothers - I just want to do my best for them. They're all like family to me too.

[hence why Tenka has that habit of adopting everyone in sight.... but even then he just laughs faintly]

That's true enough, I guess. Nothing really beats having Soramaru or Chuutarou around, even though I guess Sousei's company isn't that bad.
