Episode 5 of Land of Tanabata unfurls with Nanmaru, his spirits dampened by a string of job rejection slips, stumbling upon a dire situation. A child, victims to the scorching heat, lies unconscious, trapped within the confines of a sweltering car. Bystanders frantically summon the mother, but panic clouds her judgment, and the keys remain elusive. In this pivotal moment, Nanmaru's resolve ignites, fueled by the noble desire to use his extraordinary abilities for good. With a swift and decisive move, he chisels a cavernous opening through the car window, freeing the child from its perilous prison.
News of this heroic feat, coupled with the awe-inspiring spectacle of Nanmaru's supernatural prowess, sprints across social media's virtual landscape, eventually echoing through the halls of television. However, the police eye him warily, cognizant of the potential dangers his abilities might unleash.
Inspired by Nanmaru's legendary feat, Takashi and his compatriot embark on a rebellious crusade, etching their dissent into the fabric of institutions by gouging holes in their structures. This trend of "gauging" ignites a firestorm of rumors, casting Yoriyuki in a precarious position as the Baron interrogates him, lamenting, "This power, a rare treasure, risks losing its luster. A cheaper imitation has surfaced first, diluting its exclusivity." Yet, beneath their apparent discord, Yoriyuki and the Baron share a tacit understanding, one that fuels their collaboration.
In the tranquil Marukami village, whispers of suspicion linger around Takashi, his presence a looming threat to the secrecy shrouding their festival and the enigmatic powers it holds. The village elders, along with Sachiko's esteemed great uncle, seek counsel from Professor Marukami, whose true identity, it transpires, is not the enigmatic Yoriyuki. Meanwhile, a shocking revelation emerges: Professor Marukami has tendered divorce papers to his wife, further complicating the intricate web of relationships. Amidst these tumultuous tides, Sachiko embarks on a journey to Tokyo, her heart heavy with uncertainty yet driven by a sense of purpose.
She encounters Emi and Tagaya, gracefully entrusting a letter to the former, containing a heartfelt farewell that reiterates his inability to return, urging her not to search for him. Simultaneously, she hands Tagaya an envelope filled with Marukami's generosity, a tangible display of their trust. Meanwhile, Nanmaru and his companions embark on an innovative venture, dreaming of ridding the world of trash, a noble pursuit that fills him with joy. His abilities, once a source of turmoil, now serve a constructive purpose and promise financial stability.
Later, Nanmaru's path crosses with Sachinko, and he shares the sordid tale of Takashi's deceit, which elicits no shock from her seasoned eyes. Amidst this, Takashi's comrade falls prey to the authorities' scrutiny, only to mysteriously vanish along with the other two, a disappearance later attributed to Yoriyuki's mastery of Beyond the Window. Bereft of his companion, Takashi attempts to hold his seminar solo, only to be confronted by an indignant crowd of villagers. Chaos ensues, until Yoriyuki's entrance silences all. He eloquently dissuades the gathering, illuminating the impossibility of homo sapiens acquiring such powers, bolstering his argument with his own anomalous palm structure. He then spirits Takashi away, and Nanmaru narrowly escapes Yoriyuki's wrath, thanks to Sachiko's brave intervention.
In the aftermath, Sachiko's frustration boils over, lashing out at Nanmaru's naive optimism about using his powers for good. She swiftly regrets her outburst, offering an apology tinged with contrition. As they retreat to Nanmaru's chambers, Sachiko bares her soul, revealing enigmatic scars etched upon her flesh, each a testament to her struggles. She struggles to articulate why she dissuades Nanmaru from his philanthropic aspirations, her silence a heavy burden. Their conversation hangs in the balance, as Sachiko's secrets shroud her true feelings.
