Akkan Baby

Akkan Baby is a three volume shoujo manga revolving around the adventures of two 16 year old Too Dumb to Live rock band groupies named Yuki and Shigeru. These two meet at a concert and start having a carefree Friends with Benefits relationship until some of Shigeru's more down to earth friends mention the possibility of pregnancy. After some humor based on Shigeru's inability to read a pregnancy test, she discovers she's pregnant. Hilarity Ensues.

Tropes found in this work:

 * Door Step Baby: Yes, they find a baby on their doorstep as well.
 * Friends with Benefits: Shigeru and Yuki's relationship until romance ensues.
 * Gender Blender Name: Shigeru is usually a boys name, and Yuki can be a girls name- part of the reason that Shigeru's mom thought her always staying over with Yuki was OK.
 * Good Girls Avoid Abortion: Played VERY straight.
 * Papa Wolf: Yuki is very protective of both girl Shigeru and the Door Step Baby Shigeru.
 * Meet Cute: Shigeru and Yuki.
 * Pet the Dog: When the school principal.
 * Teen Pregnancy
 * Tinkle in the Eye: The Door Step Baby manages to pee on them too.
 * Too Dumb to Live: Shigeru asks 'what's a condom?' in all seriousness. Yuki is similarly unfamiliar with birth control.
 * Who Names Their Kid "Dude"?: The name Shigeru and Yuki settle on for their son is Muni, after the onomatopoeia for his soft round cheeks.
