Krystal knows that look. She nods at goku. “Right kakarot!” She grabs Kain and pulses her power through him, slowly feeling him, profiling him. She wanted to make him suffer elegantly. “I generally believe the sins of the father should not affect the son, but.. since your father was such a douche.. I can see into your soul, little prince. If you had been brought up right.. away from your father.. away from your mother.. you might’ve been fit to rule. But.. seeing how tarnished you’ve become..I pass judgement. For crimes not yet committed to the royal families of Vegeta and the moon, I revoke your rebirth. You will never again darken a door way.” She plunges her sword into his chest, crushing his heart crystal and starseed to ash as she made his body begin to melt away.
Vegeta nods. “Yes, that’s right, ikuko.”
