Chizuru's Development Diary (2021)

When Mafuyu Oribe and her adopted sister Tomo rescue a strange wounded man, they have no idea what they’re getting involved with or what the consequences will be. Alexander Nikolaevith Hell is an Iron Qwaser, one of many opposing factions of super-warriors.

The story takes place in Japan in the early 21st century, in an alternate reality where the Tokugawa Shogunate has remained in power. In this reality, student councils are tasked with oppressing schools. Yagyuu Muneakira is a high school student who rebels against his student council with the help of girls who've had the names of famous samurai heroes passed on to them.

The story follows teacher and veteran solo camper Kensuke, who forms a camping group with four girls.

The story follows Rena Yukuhasahi, a reserved office lady and Ryouhei Hachiya, a businessman and fellow colleague. Yukuhasahi appears to be the most reserved girl in the company, but becomes a super beautiful woman when she dresses up. Flustered in the presence of her transformed self, Hachiya insists on taking her out, only to find themselves in front of a love hotel.

Eager to follow in the footsteps of his fallen sister, Kazuya enrolls at West Genetics Academy, a training facility for buxom heroes known as Pandoras. These courageous schoolgirls are genetically-enhanced with enough sex appeal to cripple a man – and the superhuman strength to slaughter aliens by the dozen. Kazuya’s role is that of Limiter, a Pandora’s battle partner, and he quickly sets his sights on the most feared beauty in school, Satellizer el Bridget. This full-figured annihilator of aliens is as desirable as she is deadly, but rubbing her the wrong way could lead to gross bodily harm. Can Kazuya forge a bond with his new partner and rise to the top of the ranks at West Genetics? Or will he fall victim to the mysterious bloodlust lurking within Satellizer?

Hida Kizuna possesses the HHG (Heart Hybrid Gear) ability, but it is not strong enough to make him particularly important. His older sister calls him to transfer to a strategic defense school, where many of the students (many of which are large-breasted girls) use their HHG abilities to fight invaders from another world while wearing extremely skimpy pilot outfits. Kizuna's fighting ability doesn't measure up, but his sister has another plan—apparently having erotic experiences with Kizuna will allow the girls to replenish their energy or power-up. It looks like his new school life is going to be full of embarrassment.
