In the end, Ichika managed to break free from the confines of his obsessive harem and his overprotective big sister. The battles had left scars, both physical and emotional, but he was determined to move forward.
The yandere admirers and Chifuyu, on the other hand, were left to confront the consequences of their obsession. They realized that love should never be forced, and their actions had driven Ichika away.
As Ichika continued his life, he hoped to find genuine love and friendship, free from the suffocating grip of obsession. The tale of his yandere harem served as a cautionary tale, a reminder that love should be given freely, not taken by force.
The end.
