Mariko Ozono

As the teacher to several main characters, Mariko Ozono plays a pivotal role in the narrative, often serving as a catalyst for the romantic entanglements of Masa and Higure. She harbors a secret affection for Commander Beef, Masa's superhero persona, a secret she must keep. Her history is further complicated by her twin sister, Yuriko, who was separated from her fifteen years ago by a tragic event, leading to vastly different lives-Mariko as a devoted educator and Yuriko as a member of the Nebula syndicate.
