The Law of Ueki

Summary:
The Law of Ueki tells the story of the Battle of the Supernatural Powers, a tournament to decide who will be the next King of the Celestial World (rendered as Kami (天界人) in Japanese version). Each candidate (100 in total) is required to choose a junior high school student to act as their fighter. Each student is given a unique power--the power to change one thing into something else. The winning King of the Celestial World Candidate will become King of the Celestial World and the winning student will receive the Blank Talent (blank zai), a talent that can be anything they choose. While this leads many students to thoughts of greed and selfishness, Kosuke Ueki has decided to take it upon himself to win this tournament to keep that power away from those that would abuse such a gift.

Ubel Blatt

Summary :
When the Wischtech threatened to invade the fiefs of Szaalanden, the Emperor dispatched fourteen youths. Of these, three died, and the Seven Heroes halted the invasion to herald a time of prosperity while the four Lances of Betrayal were supposedly defeated.
Two decades later, the Lances of Betrayal have reappeared and formed a bandit militia near the frontier fief Gormbark. A man with a black sword and a scar over his left eye slays an entire troop of that militia. He is identified as the boy, Koinzell, and becomes as much an object of fear as of hope even as his own past, motivations, and purpose are a mystery to those he meets on his journey.
From Volume 0's back cover (SBM's translation):
"When the black sword roars, everything that stands before it is crushed . . . ! What is the purpose of a boy Kaintzel who possesses transcendent sword skills? The battle with the "Lances of Betrayal" that were supposed defeated by the 7 Heroes... And the astounding truth that is revealed after the battle."
Volume 0 encompasses a plot arc which leads directly into the main plot of Übel Blatt in Volume 1. It also introduces and develops the attitudes and motives of a few other characters aside from Koinzell.

Samurai Executioner

Summary :
The varied and bloody adventures of Decaptator Asaemon, headsman to the Shogun, and sundry other personalities in Edo law enforcement and crime.

From the creators of Lone Wolf and Cub comes Samurai Executioner. It's true! Before Koike and Kojima created Itto Ogami, they created Kubikiri Asa, better known to Lone Wolf readers as Decapitator Asaemon. He was the equal to Itto, bearer of the sword Onibocho, the man charged with the duty of testing the swords for the shogun. Samurai Executioner is based on the decapitator himself, in life before his fatal duel with Lone Wolf. Expect the same legendary drama, frantic action, and stoic samurai stature, combined with the exemplary art and storytelling that made Lone Wolf and Cub one of the most popular and influential comic books in the world!
