The upcoming season will tackle the Hawaii Trip Arc, often referred to in manga forums as the Paradise Arc — a pivotal narrative stretch that has been long-awaited by fans of KanoKari.

In this arc, Kazuya and Chizuru join friends on a tropical getaway, but paradise quickly transforms into a proving ground for feelings left unspoken. Kazuya, emboldened by both distance and circumstance, edges closer to a heartfelt confession, while Chizuru’s emotional walls begin to visibly strain.

Meanwhile, Ruka steps up her romantic pursuit, vying for Kazuya’s attention in increasingly bold ways. Adding fuel to the fire is Mami’s return to the spotlight, orchestrating psychological chaos with her signature blend of manipulation and mystery. This emotional powder keg threatens to redefine the series’ romantic hierarchy.
