An utterly ordinary protagonist enters an interstellar military academy and awakens a healing talent that disappeared centuries ago. But every use triggers a mysterious side effect.
A genius, icy-cold solo fighter who battles on the brink of death gets fully healed by one burst of healing. His stats are maxed out, but the side effect is that he can't stop calling for his mom.
The consequences of a full heal might include the straight, super-soldier Ah Pei getting pregnant, throwing up uncontrollably with a baby bump while beating the crap out of his opponent.
It's not very dignified, but there's no denying the healing effect is astonishing, and it comes with an invincibility buff.
As a result, the protagonist becomes the military academy's new prodigy and joins the team representing the academy in the league.
Later...
League spectators are laughing and crying in front of their mainframes.
Oh my god, our academy finally made it to first place in the league!
But our reputation is going to be ruined too!
(This is a simplified blurb, but the gags are staying the same. I'll write a more detailed version before I start posting.)
