Also known as: 鴛呂実レシノ
"Mrs. Estacion"
The Final Boss of Mrs. Estacion, and its titular antagonist. He is one of the few beings capable of returning Himeka from the dream world, but he initially refuses to help her, as she struck down his subordinates. Initially, he seeks to turn her into another one of his Mrs. as revenge.
Estacion is the Spanish word for "season", fitting the boss titles being named after seasons. Despite appearances, he is actually male, and despite being male, his title is still "Mrs. Estacion", sticking with the pattern of having each of the boss titles start with "Mrs."
He wields Cupid's Bow, which is capable of enthralling others into his service. This is how he was able to turn the other Mrs. into his underlings, and how he plans to turn Himeka into yet another.
