No effort required. But there are service scenes. Sasami-san has entered her second year of high school, starting a new school life. Gradually breaking free from her reclusive lifestyle, she hopes for a fulfilling school experience, but instead finds herself relying on her only classmate "friend", Kagami. Amidst this, her classmate and class representative, Edogawa Jouu, plans a "vacation trip" for the entire class. During this trip, Sasami-san might develop a bittersweet relationship with Jouu. But don’t forget, Jouu is the leader of a nefarious occult group aiming for world domination! With swimsuits, baths, and ancient god summoning, along with hidden deities and the plot for world conquest... this chaotic Volume 4 features a school love comedy filled with women and the schemes of gods unfolding simultaneously.
