Episode 5 of Sunny commences with a poignant scene, as Suzie watches Zen's school play unfold, her gaze filled with pride. Yet, Masa's tardy arrival, clutching a stuffed toy and blurting out vague "work issues," disrupts the harmony. In truth, he stumbles in, inebriated, convinced that Suzie couldn't fathom his struggles. He chastises her for not mastering Japanese, his frustration barely contained, threatening to spill over onto Zen as well.
Flashing forward to the present, Suzie awakens amidst a train journey with Mixxy and Sunny, their grand escapade to a countryside farm thwarted by a missing shuttle connection. Mixxy's unawareness of the situation compounds their predicament, and the train back won't arrive till dawn. With no mobile signal in this remote locale, they reluctantly embark on a trek.
Their journey takes an ominous turn when Suzie collides with a passenger sporting a bruised eye, who vents his frustration on a nearby vending machine, heightening their urge to flee. As they delve deeper into the woods, Mixxy's navigational skills falter, and the trio realizes they're in for a lengthy hike. Amidst jokes about Suzie's lucky underwear, Sunny keeps a watchful eye on Mixxy.
Meanwhile, in town, Noriko arrives at Sunny's abode, only to find it eerily vacant.
In the wilderness, Sunny stumbles upon a fragile black baby bird, adopting it temporarily as their uninvited companion. This chance encounter is soon overshadowed by the reappearance of the mysterious man with the blackened eye, wandering aimlessly through the trees. Tension mounts as Sunny confronts Mixxy, questioning her loyalty and hinting at her potentially treacherous nature. To compound the dire situation, Sunny confesses her dire need for recharging; failure to do so would mean her power fades, plunging them into darkness.
Mixxy's confession of being lost shatters Suzie's composure. She explains her futile attempts to recognize landmarks, only to find themselves hopelessly wandering. As tears stream down Mixxy's face, Suzie offers comfort, drawing from her own experiences of being lost and desperate. Together, they vow to forge ahead, guided by sheer determination and blind faith.
Eventually, they stumble upon an abandoned house, a beacon of shelter in the vast wilderness. Seeking respite, they settle within its walls. As Suzie drifts off to sleep, her dreams transport her back in time, to a poignant memory of Zen appearing in her room, bearing news of Masa's sudden, midnight departure, his suitcase in tow—a strange and unsettling scene that lingers in her mind.
Suzie jolts awake, her slumber disrupted by the melodic chirping, only to discover that Sunny's battery is dwindling. Her altruistic act of utilizing the incubator to nurture the helpless baby crow has inadvertently drained her resources. As Sunny's ire shifts towards Mixxy, accusing her of some unseen misdeed, a terrifying intrusion shatters the tranquility. A bear, a menacing figure from a nightmare, materializes outside, wreaking havoc on their sanctuary. The duo erupts into a cacophony of screams and shouts, their combined efforts eventually scaring the beast away. With hearts pounding, they decide it's best to venture back into the world.
The narrative skips ahead, revealing our trio's arrival at the farm, where Mixxy is joyfully reunited with her uncle. Sunny, with a heavy heart, places the baby crow within the incubator's embrace, but alas, it's too late to save the fragile life. Suzie's arrival coincides with Sunny's, profound yet sorrow it transpires that this heartache was precisely what Sunny sought—a taste of the pain Suzie carries. Her entire endeavor was a quest to comprehend Suzie's depths, a longing to empathize.
As they stand amidst the somber aftermath, Suzie recounts instances where Masa's behavior seemed eerie, tinged with suspicion. Guilt consumes her, but amidst the grief, a small ceremony is held to honor the baby crow's passing. Meanwhile, a parallel scene unfolds, where Noriko hesitates before dialing a contact ominously labeled "Do Not Answer." Inside a shower's steamy veil, a shadowy figure lurks, Masa's identity hinted at but elusive.
Sunny's mind flickers with fleeting memories, notably the traumatic moment of being torn from Masa's side. She vows to Suzie that she will strive to recall more, unaware that Mixxy stands sentinel in the doorway, observing the intimate exchange with a mix of curiosity and unease. When Suzie awakens from her reverie, she finds Sunny has vanished, leaving behind a haunting note and a hollow finger, a macabre souvenir that chills her to the bone.
