Reviving Karane’s Tsundere Spirit

Picking up from previous events, the episode begins with Rentaro divulging his plan, inspired during a night at the Hanazono residence. He discovers that anyone can create a Tsundere factor, though the current iteration of Karane is unable to generate the same intensity as her original self.
To bridge this gap, Rentaro proposes that each girl generate a smaller portion of their Tsundere Factor. He strategically sets Karane’s original capacity at 100%, intending each of his eight soulmates to contribute only 10%. This method aims to create a powerful Tsundere energy that Karane can absorb effectively.

Rentaro’s plan hinges on the varying strengths of each girl’s Tsundere energy. Acknowledging the potential chaos that might ensue if combined improperly, he wisely decides to partake in the Tsundere-fy potion himself. This allows him to unify their energies while mitigating any risk of Karane being overwhelmed during absorption.
The operation, dubbed “Operation Tsundere Festival,”is met with enthusiasm. Each soulmate participates, consuming the De-Tsundere-Fy potion to manifest their Tsundere selves, leading to an electrifying display of their unique personalities.

The collective effort successfully produces a Tsundere energy akin to Karane’s original. Encouragingly, Rentaro experiences shifts in his demeanor, gaining newfound appreciation for Karane’s past struggles to embody her “cute”self. This reflection motivates him to ensure the operation succeeds without a hitch.
As the bright light of energy surrounds them, Karane finally absorbs the concentrated Tsundere Factor. With the light fading, audiences witness her transformation back to her dynamic Tsundere persona, which brings joy and relief to the entire Rentaro family who eagerly surrounds her.
