An Echo of Determination: Isekai Investigation Unit

The world is in Peril, The Dragon balls had no power in the first place. The only hope we have left. Is a person who can't seem to shut up about determination. This is also far from a standard Dragon ball world. Also, What's this about an Isekai investigation unit?

"Heya. You've been busy, huh?" I look around at the devistation King Piccolo has wrought. . . .
(King Piccolo Power level 9800)
"So, i've got a question for ya." Piccolo looks at me, and says. "You know nothing. When I killed you're friend Goku, I thought You would fight me at your full potential." I continue as if I wasn't interrupted. "Do you think even the worst person can change?" That everybody can be a good person, if they just try?" I start to laugh. afterall, I, An Otaku, am the last person alive on this planet. "All right. Well here's a better question. Do you wanna have a bad time? 'Cause if you take another step forward- You are REALLY not going to like what happens next." Piccolo swipes his Arm at me. in a forward chop and I dodge, "Welp. Sorry, Goku. This is why i never make promises." energy starts to crackle around me as the sky turns dark. (The Echo Is Resonating with your determination. All Physical Aspects have been Increased.) "It's a beautiful day outside. Birds are singing, flowers are blooming. . . On days like these, kids like you. . . Should be burning in hell." King Piccolo continues to use more esoteric martial arts. every kick dodged, every swipe missing by a hairs breadth. "You think I'm just gonna stand there and take it?" I charge, "MASENKO!" SHIT!
I die. But not for the first time.
(The Echo Has Granted you a boost in your Reaction speed and Kinetic Movement. Try again.)
