Synopsis: A Springtime with Ninjas

Benio, the heiress of the wealthiest family in Japan, is expected to marry the person who kisses her first, as per tradition. In order for her to attend high school safely, she is assigned a ninja bodyguard named Tamaki. However, Tamaki's promiscuous behavior poses a challenge for Benio, who is independent and strong-willed. This romantic comedy delves into the challenges faced by a virtuous young woman and her handsome protector, who may be a tad too clever for his own good. Volume 1 also includes a one-shot manga titled "Ninkoi," which serves as a pilot chapter.
