Unlike Kent's past life as Kevin Sage, who hated his siblings from his mother's side, Kalimndra, the lazy prince whom many looked down on, loved his big sister dearly.
She had protected him when many thought he was useless. And when she discovered his secret identity, she didn't expose him as most people would have.
She understood him and knew letting him continue as he was would be helpful to him. So for several years, Kalimndra maintained his peace.
Because of this, he had grown grateful to her, and so when he saw her get pulled into an unfamiliar portal, Kalimndra became so furious that he went all out, breaking his limits and unlocking so much power that by the time he reached a certain point of power, everyone had stopped fighting and simply watched him decimate the Sun Demons until the very last one.
Everyone has their reverse scale.
