First impression is that this will lead to a love triangle, but will be pleasantly surprised if it doesn't. If let's say Anji likes someone else (esp. if it's a guy) there will be much drama. I think it would be awesome (if it doesn't go towards yaoi/shounen ai) for Hiiro to go total fujoshi on Wakana and Anji (which it already seems she is open to free love) because at least if it won't be a yaoi there can be major bromance moments.

I love this manga, while looking for a good gender bender I found this gem! Sadly after the third volume there is a hiatus, and there is no ending! If anyone can understand/read&write Japanese here is a link to the artist's website: http://77x16.com/?cat=3

All I could get from that site is that it's not in print. It might be that the publishing company dropped it, but the site doesn't provide a detailed explanation.
