From Yen Press:

One fateful day, Ryousuke Kaga, a typical hopeless romantic and hopelessly perverted high school student, has a chance encounter in the rain with a beautiful girl. After graciously offering both his home for her to dry off in and his help for anything she might need, the mysterious red-eyed beauty thanks him by stabbing Ryousuke in the chest! To further complicate matters, the girl, Lisara Restole, is actually a shinigami–that is, a god of death–and Ryousuke has somehow unwittingly agreed to let her use his “essence” to remain in this world. But instead of shaving years off his life like one might expect of a typical shinigami, Lisara seems more interested in…leeching the letch right out of him?!

From Manga Box:
Satoru Hasegawa, a young real estate agent, lives together with his equally young wife, Aya, and their daughter. Five years into their marriage, he's not particularly dissatisfied with anything, but he's got a secret that he can't tell a soul! Satoru is helpless before Sayaka, an escort, and Eri, his boss at work, and he's been carrying on lively affairs with both of them. But then he meets a woman with the faint aura of first love... This is a romantic suspense story about a man who can't tear his eyes away from that sweet but dangerous trap.

Based on the Garouden manga. A short 2 volume manga about two males whose goals are to become number one in life (and their success). The plot outlines the protagonist, Tanba and a former sumo wrestler turned high school teacher, Kiriu and their head to head combat, from the eyes and views of the main character, Shinichi Kido.

This is all about a 16-year-old guy named Gan (family name: Goda) who, along with his various fighting-video-game-styled pals, opposes the very naughty Hanged Cross gang on an alarmingly regular basis.

As the story begins, Gan is a juvenile delinquent who has been booted out of one too many schools for chronic bad behavior. Gan's father, a hotdog supercop with the moniker of "Dan Goda," is fed up with this situation to the point where he decides to send Gan to his old educational institution: a fighting school called Roujuu Private High School. There, Gan learns to harness his raw abilities into "Gunfighting," the family martial arts style resembling firearms. Think .44 Magnum punches, Shotgun Fists, Sniper Stances, and you've got the essence of Gun-Fu down.

At his new school Gan also falls madly in love hot chick, Yuki and runs afoul of 17-year old transfer student and sure-to-be-rival Garrick Rider, prodigal master of the Hanged Cross technique. Fights over Yuki's affections take place in the school stadium, but it turns that she has little need for defenders of her honor. Yuki is, like an overwhelming majority of students at Roujuu, a fantastic fighter. And from here on out, everbody is not only "kung-fu fighting," but also busy filling pages with over-the-top battle scenes.
