Rentarou gathers the group on the roof to explain his plan to restore Karane's tsundere personality. Since Karane is unable to produce any tsundere energy on her own, Rentarou has the idea of harvesting tsundere energy from all the other girls using Kusuri's tsundere drugs. Rentarou would collect all the tsundere energy in order to combine it into a single mass that Karane could then intake more safely than ten masses one after another. All the girls agree to the plan and one by one provide Rentarou with their own flavor of tsundere energy.
After three hours of continuous efforts, Rentarou has collected enough tsundere energy to match Karane's original personality and proceeds to "spirit bomb" Karane with the ball of tsundere energy. The girls all cheer her on as she attempts to absorb the energy.
When the dust clears, Karane is back to her old self. Though she is annoyed that still being able to show the slightest hint of kindness has everyone thinking it wasn't a complete success.
Tropes:
- Continuity Cavalcade: Right before Rentarou "spirit bomb"s Karane, a flood of panels showcasing Karane's memorable moments takes up an entire page.
- Shout-Out: The plan to restore Karane's "tsundere-ness" is explicitly compared to the Spirit Bomb, with Rentarou as Goku and Karane as Majin Buu. Said plan's possible failure is correspondingly compared to Vegeta's "Dirty Fireworks". Hakari also volunteers to be Chi-Chi.
