Now this is a story all about how Natsu's life got flipped-turned upside down~! So, Romeo challenged his hero to a fight. Pretty simple. Natsu took him up on his offer and didn't think much of it. He should have though. It really didn't take long for Romeo to beat him down to nothing but his underwear, putting him into a wrestling clutch and then punching him to high heaven. Afterward he dropped Natsu in front of the guild after putting him into a diaper for emphasis of his dominance. The guild acknowledged Romeo's accomplishment by letting him go on more missions as a higher class while a new proposed "Baby Class" for diaper baby mages was made. It's the lowest of the low and he's the only one in it.
How did Romeo get enough power to overcome him? He did 100 squats. 100 sit-ups. Ate his breakfast every morning and jogged lightly for a good long while. The Saitama "One Punch Man" training regime works! Try it out for yourselves.
