VIVI said: -The thing in the middle of the chest of Hisao is something who can read people hearts. -Part of the hair of Hanako looks like flowers. -The tentacles of Lilly are semitransparent, and she can see in diferents "levels" (ultraviolet,infrared,x ray etc.) -Rin can change her arms of color with her emotions. -Emi have "eagle eyes", too. -Shizune hear things who even a dog can´t hear, but is too much for her, then she use ear protection always. She can´t control all her mouths, sometimes. -Misha have one "drill tentacle" who can spin. And now she have a plus: now is a futa (and is happy with that) -Kenji can see things who we not...even in the dark (then his eyes can shine...brr) but can´t talk (his vocal cords...dissapered) and only can "speak" with Hisao. And is exactly a weird thing, worse than a futa (the spores screw him to the point to turn him a male-she,male but adding vag, happily infertile) obviously he hate it, but at least this can´t be saw in first sight. this imagined meanwhile draw each one.
