Dragon Raja: Oh no! Lu Mingfei has been diagnosed with depression!

Kassel College is having some trouble lately because their newly recruited S-class students seem to be acting strangely.
During his day of freedom, just because someone shot him in the dark and scared him, he turned around, pried off a brick, and knocked out concussions from everyone present.
He joined the Kuimen Project simply because Nuonuo said to him, "You still have a lot to experience," and he immediately plunged into the water to fight the next generation of the species.
He went to Tokyo, Japan, but because he was betrayed by the Hebi-Hachi family, he turned around and set fire to the Hebi-Hachi family's shrine with a gasoline can on his back.
"Lu Mingfei is not crazy, he just suffers from depression. We should understand him and cherish him."
"That's what Masafumi Tomiyama, a psychology professor at the academy, said."
"I don't have depression, I just suddenly have a breakthrough."
Lu Mingfei knocked out the guy who was spreading rumors about him with a brick.
"Brother, shall we trade? A quarter of my life..."
"Such a good deal? I'll go all in!"
The little devil was stunned.
Thus, the person least susceptible to pressure in the world of Dragon Raja was born.
