Toaru Majutsu no Index - Volume 8, Chapter 1: After School of Girls. After_School_of_Angels.

There’s nothing that Yu Wan has in common with her new neighbor– whether it’s charisma, personality, or cooking skills– other than that they both own dogs. Their two cute pets get along well (a bit far too well) and start what seems like a rocky friendship between the two; however, Yu Wan has more important things to worry about. Her wildly popular novel is about to take off into a drama adaptation, but the handsome, mysterious, and callous neighbor- is the director?!

Shen Qingzhou (as he thinks of someone): I’d say three. ]

I was left paralyzed with only a month to live, but that “9-inch” part of me was still hard as a rock. Even the sickly beautiful schoolgirl couldn't resist my “pecker,” and to fulfill my dying wish, my sister even dressed up as a lady in black stockings to teach me how to “drill.” What's more outrageous, the hospital nurses wanted to make a little movie with me, lining up with the head nurse at the front...Just after coming out of the emergency room, I saw the system panel:Name: Ethan JonesGender: MaleLength: 9 inchesSkill: Hard as a Rock LV1Note: Peak human hardnessDying Wish: To caress auntie's sheer black stockingsTask Reward Points: 1000 pointsDespite my strength and stamina attributes being only at 1, and my agility at 0, only my “pecker” could lift the heavy blanket while doing squats. My face was full of question marks—what kind of bug is this system? Just because I like looking at auntie's legs, did it give me such a special skill?Now, I have no choice.
