Alas, Makoto does not strike me as the most delicate of people. Kanon seems to be much more so, which is good because Akari is probably the only other person capable of some delicacy in the whole group. I would imagine that the Ganma part is the only thing that makes her feel possibly unwanted at home-- I can't see Makoto and Takeru et al. being anything less than devoted uncles and aunts.

I meant "something else" in terms of "something else none of her friends have to worry about" but forgot to clarify.

Oh, so Riko has an aunt who has talked to her about supernatural stuff. Has the aunt met Chiyo?

Yeah, I would imagine that Chiyo would be absolutely terrified of explaining it to anyone else.
