Toboso, Yana

Tucked away in the English countryside lies the ominous manor of the Phantomhives, a family which has established itself as the cold and ruthless "Queen's Watchdog" as well as the head of London's criminal underground. After a tragedy leaves the Earl and his wife dead, many are shocked when their son, a young boy named Ciel, claims his place as the new Earl of the Phantomhive house. At first, many perceive him only as a child surrounded by a few eccentric servants. But they soon begin to realize that it is foolish to meddle with Ciel and his demonic butler Sebastian.

Taking place at the end of the 19th century, Kuroshitsuji follows these two as they face countless mysteries and dangers that plague England and threaten the Queen, uncovering the truth about what really happened to Ciel's parents in the process.

The Kindaichi Case Files

金田一少年の事件簿

Takahashi, Kazuki

High school student Yuugi Mutou spends his days being bullied between classes and his nights playing board games and solving puzzles in his bedroom. Yuugi's penchant for gameplay comes from his grandfather, whose game shop also serves as a house for the two.

One night, Yuugi manages to solve the Millennium Puzzle, a seemingly impossible challenge that awakens his inner darkness and converts it into an alternate persona: Yami Yuugi. Transforming into the more bold and dangerous persona against his will in moments of great distress, Yuugi begins to moonlight as a vengeful vigilante, challenging bullies and evil-doers to risky games where failure results in fates worse than death.

Yuugi and his alter ego befriend some of the very students who once bullied him, forming unbreakable companionships with them. But the group must contend with villains far deadlier than the high school punks they originally rallied against, enemies who use games for nefarious purposes and threaten Yuugi and his friends' very lives.

The Good Witch of the West

西の善き魔女

Chiba, Katsuhiko

The novelization contains four sections:

The first section covers Yuugi solving the Millennium Puzzle.

The second section covers Yuugi's first encounter with Seto Kaiba from the manga.

The third section covers the second encounter with Kaiba in Kaiba Land. It omits many areas that don't deal with the card game.

The fourth section is an original story, occurring only in the novel. Two weeks after Yuugi's battle with Kaiba in Kaiba Land, Yuugi gets a call from Kaiba, who tells him to meet for a Duel at the top floor of the KaibaCorp. Yuugi accepts, and when the duel begins, they use a special variation called the "Bingo Rule," which prevents the used of a specific card in each player's deck. Kaiba seems to be himself, but plays a different trump card, the "Automatic Giant."

Mokuba stumbles in on them, and tells Yuugi that Kaiba has not yet awoken from his catatonic state. It turns out that the Kaiba that Yuugi is playing against is a Cyber Kaiba, controlled by the KaibaCorp computer, and using all of Kaiba's memories.

Yuugi defeats the "Automatic Giant" and Kaiba with a card called "The Unknown Egg."
