Domina no Do!

Tsuchie Takeshi fondly recalls his childhood days spent playing with a girl named Hikari, remembering her as a kind and gentle companion whose sweet nature left a lasting impression on him. That innocent image is abruptly overturned when, on his way home from school one day, Takeshi is abducted and carried off to an enormous mansion. Waiting for him there is the very girl from his memories—except the Hikari he encounters is no longer the gentle child he once knew. She has transformed into an arrogant, violent dominatrix, and to make matters even more bewildering, she boldly declares that Takeshi once promised to marry her. Now swept into a life he never agreed to, Takeshi must come to terms with Hikari's startling new personality while adjusting to his place as the newest son of her prestigious family. Living under the same roof as the domineering girl of his past, he faces the daunting challenge of surviving each day beside a childhood friend who is nothing like the person he remembers.
