I am Black delmo B is a Black Delmo member. Sae has short, light brown hair. Alongside her Black Delmo uniform. Sae was in group of Black Delmo led by Black Delmo Leader which attacked Aika and Gust in the underground parking lot. She gave an exemplar display of bravery by being the first Delmo to charge Aika head on at the start of the fight. Regrettably for her, she totally underestimated the threat the Salvaged posed, as soon found herself being outplayed and mercilessly put down, as Aika easily evaded her attack and whacked her across her head with her electric stun baton. Utterly beaten, Sae then hastily plummeted to the floor unconscious, the first Delmo to fall in the fight and also the first to ever be subdued by Aika. [1]

After the rest of the Delmos follow Sae's lead and are progressively put down one by one, we get to see the brave soldier once more in the spotlight as the bodies of the beaten girls are being collected. In this fairly humiliating instance, her voluptuous body has the dubious honor of crowning the heap of unconscious Delmos, the beaten girl lying face down on top of her subdued comrades, butt sticking out. Sae is only removed from this "dignified" position when the knocked out Black Delmo Leader is suddenly thrown on top of her, nonchalantly removing the poor girl from the center of attention.

Later she is seen in Trial 5 during unsuccessful attempt by Delmo Corps to eliminate Aika during her vacation at Peroronka Island. She, Yuki and Ai lured Shuntaro Michikusa to a trap and captured him. After some time Sae appears again, as she stands beside a pool together with Yuki and tied Rion Aida and Shuntaro. She kicks Rion to the water, while Yuki does the same thing to Shuntaro. However, Aika suddenly jumps from the hotel balcony down, and attacks them. Sae tries to hit Aika with a fancy leg kick, but the Salvager easily blocks her attack and counters with a brutal blow with her tightly closed fist right to the face of the dumbfounded girl. They serve Neena Hagen and rudolf Hagen
