Even two against one, they were no match for Casio.
Two veteran fighters, challenging a double-topped fighter? How dare they?! Not long ago, Casio fought five opponents single-handedly, defeating three ordinary fighters and two veteran fighters. The two from the Blood Spirit Association pose no threat!
Since they pose no threat to Casio, it is now their turn to feel threatened by him. What goes around comes around, reciprocate pleasantry for pleasantry.
Casio travelled from afar, a meeting is as good as fate. Without taking anything valuable from the relic, he decided to take these two lives again. After all, seeing once brutally defeated opponents jump around in front of one's eyes tends to soil the view. Casio is a bit of a clean freak.
"Crunch, crunch, crunch..."
The sound of moving rubble came from beneath the tunnel.
"Since you've come back from the dead, let me send you off again!"
