KLK is an original anime that has it all: action, drama, comedy, ecchi, mystery, twists, high octane music and crazy animation. The ecchi can be spicy but I think not too much for your trio reactions. No sex scenes, just partial to full nudity that’s censors the bits. It’s more through how unhinged and unashamed the characters are in their outfits.
Basic premise of the show follows a female MC who’s on a journey to solve the mystery of who her father’s killer is. This takes her to a school that uses strange uniforms that grant amazing abilities. She must fight her way through them so she can get at the boss bitch of the school. Battles always end with the loser being literally “STRIPPED OF THEIR WILL TO FIGHT!” Also the ecchi actually plays into the plot and power system, which always enhances it.
It’s one season, 25 episodes, so not too long of a commitment if you decide to watch it. I really do believe you guys would love this.
