You thought Daisuke is the master of the harem, but nope. Kono Asahi-sensei da! So THAT explains my question last week about her not explicitly showing romantic interests in Daisuke. He is a part of her harem, not the other way around.
And a love letter next week!? Seeing the cover of this chapter on twitter already got me excited, but now I have to wait for another week for something even better!? Masahiro-sensei you glorious bastard!
Also, we didn't see a lot of fanservice in Ika Musume (Cindy aside), but damn can Masahiro-sensei deliver good fanservice when he wants to.
