A Comic Anthology done by various mangaka based on the game, Tales of Symphonia.

Once upon a time in a fantasy world plagued by war, a group of four brave souls challenge the source of all the evil. It seemed all was lost until one of the heroes defeated the enemy with a powerful spell. The four heroes were able to seal this great evil to be forgotten forever - or so they thought. The next scene in this story takes place years later with the children of those who sealed away the great evil. The sealing was accomplished by combining the power of two pendants. A foolish dark knight is somehow tricked into stealing the pendants, to break the seal that conceals the great evil. He defeated the heroes and kidnapped their children. With the two pendants in hand, he broke the great evil's seal. A remaining hero sends the children to another time so that, maybe, the world will have another chance. What will become of the children? How could they possibly defeat someone that their parents could only seal away? Who is the great evil and what is his purpose? Only time will tell as they venture on into several strange, yet familiar worlds.

From Snow Kiss Scanlations:
Once there was a legend of a sword. It is said that the sword of a rune god was sealed up in "Jagara-Mogara". When the spirits of Light, Water, and Earth come together, the seal will break, then the sword will be immortalised. That is the sword of Susanoh.
Izumo, Kumaso, and Oguna, upon pursuing the sword of Susanoh, came to the nation of Jagara ruled by an Empress and her army of women. They got involved in the wars between Jagara and Amamikado, but what awaits them isn't the clash between two nations, but the darkness involved with the sword of Susanoh that everyone is seeking.

In 2071, north pole ice have melted and the land has been submerged. Humanity survived but it's divided into two species: the true humans, those who live in underwater cities, and the Dugons, those who chose to undergo genetic modification to live in the sea. Both species go to war to survive as long as the Dugons consider the humans good to eat.
To defend against the Dugons, the city of Mari Ramelle builds a new kind of weapon, the mermaid robot, Salacia. Because of the small size of the the pilot cabin, the robot is piloted by a girl and a boy, both 13 years old: Marin Yuuki and Ushio Mizushiro. The fight for survival is hard, and during the manga, the city builds more mermaid robots.

In 1867, he and his close friend Nakaoka Shintaro were assasinated before his dreams could be realized.

Tenshou no Ryouma explores the historical alternative-universe where Ryouma is saved through Shintaro's sacrifice. Given this second chance, will Ryouma finally be able to establish a new, modern Japan?

International man of mystery and master thief extraordinaire, Lupin III comes from a long line of high stakes bandits, all committed to stealing from the rich and giving to themselves. Fortunately, Lupin tends to avoid robbing society's virtuous and, instead, targets some pretty shady characters.
Of course, he partners with some pretty shady characters as well: Daisuke Jigen is an ex-mafia hit man who carries himself with a somber demeanor, his trademark black fedora tilted forward to hide his eyes. Goemon Ishikawa is a cipher-like swordsman with samurai-ish overtones who mysteriously fades in and out of Lupin's exploits. Fujiko Mine is the object of Lupin's affections, but, since she is a thief herself, the duo's romance more than occasionally clashes with their competition for big scores.
The global police force, Interpol, and in particular the tenacious Inspector Zenigata, long to capture Lupin and his gang. Zenigata's relationship with the eponymous master thief is a complicated one, characterized by mutual respect laced with utter disdain. The two have even worked together when it's served both their interests, but they understand that when the crisis ends, they must resume their former wariness and animosity toward each other.
