In Hawk Moth's lair...
"Ah, Mother's Day. A special day to celebrate with your mothers, and a day of fools when it comes to the deceased mothers," he said as his window opens to create the villain. "Such negativity for two akumas to be used for this special occasion."
Two butterflies land on his hand and fills them with dark energy to convert them into akumas.
"This should help give them a sibling rivalry."
The akumas fly away from the lair and the first one it went to Rumi.
"Releaser, your older sister is always suppressing her sadness about her mother's death," Hawk Moth spoke to her first. "Too bad she can't keep it like that forever. Which is why I'm here. I can give you the power to make her cry. Is that okay with you?"
"I'm going to make Sister wish she never stayed happy on Mom's death!" Rumi turns into Releaser, a supervillain with an appearance of a sad clown, including the mascara running down each cheek. She uses a honking horn as a weapon. In fact, she tested it out on two civilians as it let out what they have been suppressing.
The next akuma went to Nanami.
"Suppressor, you've locked away your sadness ever since your mother died," Hawk Moth spoke next to her. "It seems your younger sister can't follow this idea of yours, but worry not, I can give you the power to lock her heart forever. Is that a deal?"
"I'm going to teach Rumi how I feel!" Nanami turns into Suppressor, a supervillain with an appearance of a goth and uses a broom as a weapon. In fact, she tested it out on a civilian who with one hit is suppressing his emotions.
