The 162nd Suggestion: Everything About Hakoniwa Academy (箱庭学園のすべてが, Hakoniwa Gakuen no Subetega) is the one hundred and sixty-second chapter of the series Medaka Box.


Shiranui pretends not to remember her visitors, claiming she forgets quickly about unimportant things. Obi is pleased with Shiranui's response to her friends, noting that the girl is the embodiment of the Shiranui Village. In response to Shiranui's cold greeting, Medaka makes a dirty joke, and demands refreshments, surprising Zenkichi. At Medaka's refusal to leave, Obi orders Kairai to bring them tea, while she goes to check on Iihiko. Ajimu notices when Obi leaves.

Seated and with tea, Shiranui drops her earlier act. Listening to Shiranui, Zenkichi demands to know if all she did was simply part of her job. He is visibly hurt when she responds in the positive, and tells him that she only became his friend to get close to Medaka. Shiranui goes on to question Kumagawa as to why Zenkichi still has his memories, but then dismisses him before he can answer. Medaka asks the other girl why she tried to erase everyone's memories before leaving. Medaka goes on to say that if Shiranui's true feelings are that she desired to be pursued, then they will work towards that. Shiranui laughs, before revealing that she always hated everything about Hakoniwa Academy. After expressing her true feelings, Shiranui tearfully begs Kumagawa to erase her memories, only to become more distraught after he tells her he cannot. In the face of Shiranui's plea, Kumagawa admits it is impossible. Offhandedly mentioning that his current fetish is an open-front hooded sweatshirt, he goes on to explain that his All Fiction has deteriorated to the point he cannot erase things that hold a strong emotional attachment. Because Shiranui's feelings are still with Hakoniwa Academy and Zenkichi, he cannot erase them. Zenkichi asks if she cannot return at least for the third semester, so that she can say a proper farewell. Shiranui smiles sadly and tells him she has to stay in the village. She begins to explain about the darkness sealed away, before being interrupted by Iihiko. The giant (using Obi as a club) breaks through the wall behind Shiranui, sending her flying into another wall, where she drops to the floor unmoving. Zenkichi is horrified to see what the giant has done to Obi and Shiranui. Though bloodied and being dragged around by her leg, Obi smilingly tells Iihiko to entertain their guests. Ajimu tells the others to run, revealing that she can only hold Iihiko off for fifteen seconds.
