Yuna Yunis from *The Legendary Hero is Dead* is a reformed tsundere, who had a dose of truth shoved in her face by seeing Touka's memories. Realizing her perverted childhood friend was the one who protected her years ago, she stopped being mean to him, but the damage was already done.

Unfortunately for her, she traumatized him so much with her years of beatings that her love confession went over his head. He first assumed she loved him like a little brother... Yuna told him it was romantic love, but he thought it was too good to be true and talked himself into believing he was imagining things, thinking if he interpreted it that way, she would beat him up.

Yuna tried kissing him to get through, but stopped herself upon realizing he was in the Legendary Hero's body, and it might just confuse him more. Instead she stripped naked in front of him to get the message across, but while Touka enjoyed the sight, he is later shown to have no idea why she did it.

Fast forward 3-4 years to the sequel manga and Touka's harem lives with him in his house. Yuna has made zero progress due to him being equally dense. After another confession fails, she sulks, but believes it's only fair she suffer the same amount of rejection to atone for years she rejected Touka... She hasn't given up, and actively spends her days running interference to prevent the other girls from making any progress either.

Yuna Yunis was the ONLY tsundere who got what she deserved...
