In the second installment of "Blue Eye Samurai," entitled "An Unexpected Element," Mizu's odyssey continues, interwoven with fresh challenges and looming perils. The episode kicks off with Mizu weaving through a labyrinthine cedar forest, desperately trying to elude Ringo, who persists in shadowing her despite her repeated, firm rejections of taking him on as a disciple. Their interaction is laced with a palpable tension, as Mizu's frustration at Ringo's relentless pursuit and inquisitiveness about her blended heritage boils over. Ringo's innocence is evident as he pledges to guard her secrets, yet Mizu's patience reaches its breaking point, culminating in a harrowing instant where she brands her sword at his throat, warning him to never utter her gender again.
As Mizu nears a river crossing manned by vigilant guards, she bears witness to a grim spectacle: a man being meted out punishment for attempting to bribe the watchmen. This grim tableau underscores the unforgiving nature of their world. On the cusp of retreating, Ringo intervenes with a travel permit belonging to his father, deceitfully portraying Mizu as his apprentice chef. This adept maneuver enables them to sail past the checkpoint, underscoring Ringo's ingenuity, despite his clumsiness.
Upon their arrival in Mihonoseki, a port town teeming with the lively ambiance of a festival, Mizu endeavors to charter a boat to the island where her quarry, the white man, resides. However, the revelry throws a wrench in her plans, as no vessels are available for hire on that very day. While Mizu hones her skills on the towering cliffs, Ringo immerses himself in the town's vibrant revelry, further highlighting their starkly contrasting approaches to navigating the present circumstances.
Flashbacks peel away the layers of Mizu's intricate past encounters with the Swordfather, revealing a collaborative endeavor to forge a blade for a vengeful bookbinder whose singular purpose is to avenge his father's untimely demise.

Meanwhile, the Four Fangs, a quartet of assassins under Heiji Shindo's employ, trail Mizu to the treacherous cliffs. Their confrontation ignites into a thrilling battle, showcasing Mizu's prowess as she leverages her agility and training to outwit her adversaries.
The episode's climax unfolds in a dramatic confrontation between Mizu and Chiaki, who reveals himself as a formidable foe from her tumultuous past. Their battle is a fierce clash of strengths, with Mizu relying on her extensive training and experiences to stand her ground. However, the cumulative injuries from her previous encounters take their toll, culminating in a heart-wrenching moment where she collapses from excessive blood loss, just as Taigen arrives on the scene, sword drawn, ready to reclaim his lost honor.
