Based on DS Dating Sim "Love Plus."

Mazinger Angels chronicles the adventures of four women who pilot giant robots in the Mazinger vein. The concept is a spoof on the late 70's and early 80's popular TV series Charlie's Angels.

Three of the robots, Aphrodite A, Diana A and Minerva X are from the original Mazinger Z series, while Venus A is from the Great Mazinger series. Their pilots are also traditional characters from Go Nagai's universe, Sayaka Yumi and Jun Hono from Mazinger Z and Great Mazinger respectively, and Hikaru Makiba and Maria Fleed from Grendizer.

The style of the manga highlights the sex appeal of both the characters and the mechas, sometimes similarly to the way Aika's female characters are shown. (taken from wikipedia)

From Mangascreener:

Nawoki Karasawa is one of the longer-active and more prestigious names in the typically small time, lesser-known world of gag manga. In a genre where art skill is second to just about everything else, Karasawa's dialogue is hilariously sharp and witty.

A gag parody of Shinji Nagashima's immortal "Mangaka Zankoku Monogatari" (Karasawa's title only differs by adding "Chou" (super) to "Zankoku"), a manga about the dreams, ambitions, and suffering of a group of bright young mangaka. Karasawa brilliantly takes the piss out of just about everything involved with being a mangaka. It's lewd, raunchy, endlessly cynical and laugh-out-loud funny.

Originally published in Ikki and the Big Comic Spirits special issue "Casual" from 2000 to 2003, it was collected into a single book in 2005.

From Clamp no Lumiere: Murikuri is the story of a popular pig, a pervert santa claus and his high school girlfriend, nice aliens and many more... It does not make sense and I would advise you to not try to understand it. Murikuri is to CLAMP what special halloween is to the Simpsons, a collection of short gags.

Hot blooded manga about... writing manga. There are actually a few series starting with Moeyo Pen (Burning Pen), then later on came the sequel series Hoero Pen (Shouting Pen).

From Mangascreener:
In a different world than the one we live in, a world where Japan is the lone superpower of the world, there is a wildly popular game show called the National Quiz. Every night, people dreaming of riches, fame, vengeance, and happiness compete on the show, for the chance to be granted a wish, any wish they have: the National Quiz has the power to make your wildest dreams come true. It also has the ability, if you lose, to make your life a living hell.

This is the story of K-i K-ichi (aka prisoner KK47331), a former actor-turned losing National Quiz contestant-turned wildly popular host of the show, and the people and events surrounding him.
