In the decaying forests of Shima, sixteen-year-old Yukiko narrowly escapes a monstrous oni's attack. Her thoughts are consumed by her father and a mysterious samurai. As she fights back with her tantō, a mythical arashitora, or thunder tiger, intervenes, saving her from certain death. The creature's fierce battle with the oni leaves Yukiko in awe, but the chaos overwhelms her, and she loses consciousness.

Shōgun's Impossible Demand

Yoritomo demands a thunder tiger

In the oppressive heat of Shima, Shōgun Yoritomo declares his desire for a griffin, a creature thought extinct. His loyal minister, Hideo, is shocked by the demand, but Yoritomo insists it is a divine vision. Despite skepticism, the shōgun orders a hunt, sending Yukiko's father, Masaru, the renowned Black Fox, on a seemingly impossible mission to capture the mythical beast. This sets the stage for a dangerous quest that intertwines the fates of Yukiko and the arashitora.

Gambling and Consequences

In a smoky gambling den, Masaru indulges in lotus smoke and saké, ignoring Yukiko's warnings. His friend Akihito advises caution, but Masaru's luck turns, leading to a violent confrontation. Yukiko arrives just in time to defuse the situation, revealing her father's status as a servant of the shōgun. Despite the chaos, Yukiko's quick thinking prevents further bloodshed, highlighting Masaru's reckless nature and the strain on their relationship. This incident underscores the personal challenges Yukiko faces within her family.

Despite the crew's efforts, the arashitora's fury proves too much, and the ship is critically damaged, forcing Yukiko to make a daring escape with the creature. This marks the beginning of Yukiko's alliance with the arashitora.

Survival in the Wild
