Well visits the church where Cardinal Hohenheim introduces his granddaughter, Elise. Thanks to the Cardinal`s clever manipulation of their conversation, Well is soon engaged to Elise, but he finds himself conflicted at the way all these nobles view political marriage as the natural course of things. Though Well isn`t entirely opposed to being with Elise, who`s known as "Saint" Hohenheim.

Well is forced to participate in the kingdom`s martial arts tournament due to his nobility. However, he quickly gives up hope of winning when he learns that magic is prohibited in the tournament. Meanwhile Er, Iina, and Louise also decide to participate. While Er was taking it lightly at first, certain developments cause him to promise that he`ll win it.

Now that Well and the others are 15-year-old adults, they officially form their adventuring party, the Dragon Busters. However, before they have time to enjoy adventuring they receive a mandatory quest from the kingdom and venture deep into ancient underground ruins that no one has yet to return from alive. Well and the others are transported deep underground by a trap, and what awaits them there is...

Well receives an enormous reward for his exploration of the ancient ruins, garnering the envy of other nobles. He also learns about the rumors of his death. So when Well decides to leave the Capital, he asks Roderich, the man who constantly sought to become his retainer, to take charge of his mansion. Roderich is moved to tears and immediately begins acting to pin down the culprit behin the rumors.

Well is forced to make an unexpected return home when Duke Bleichroder asks him to purify the undead lurking within the Enchanted Forest. Yet what awaits him at home is his openly hostile eldest brother Kurt. Well intends to leave as soon as he completes his quest, but he`s forced to remain there without ample explanation.

Well is made painfully aware that he still doesn`t understand nobles by a few words from Brantag. To make matters worse, he learns about the plots of his brother`s wife Amalie, the people living in his homeland, and the royal palace, leaving him less and less room to maneuver. After debating it for a while, he finally makes up his mind and takes action.

Kurt obtains the Dragon`s Flute and appears before Well and his comrades, planning to kill them. However, the magic item he obtained was actually the Flute of Malice, a cursed item which gathers malice and turns the user into an undead. After unwittingly living up to the expectations of those longed for Kurt to be overthrown, Well takes his greatest gamble yet...
