Ooh, that sounds like it could work. But now the bigger question... what it could be? Maybe... someone rigged a huge bomb to blow up Atlantis for some reason and Yu caught them in the act and tried to stop it? Like, it could've blown up everything, but he actually minimized the damage?
mario is red, i am green, i try my best, but everyone's meanI think people would notice pirates invading... (though it would be incredibly ironic if Jack was the captain of those pirates) Now what kind of enemies has Yu made- oh my god I totally remember now. Okay okay, give me some time, I think I got something now. Thanks!

Testimony
On the night it happened, I was walking through a particularly quiet street when something I didn't expect happened. I was confronted by an enemy of mine, his name is Zagi. How he slipped in without notice, I wouldn't know. He challenged me to a fight and I had to accept or he would have killed me right away.
We started fighting, and for a while I thought things would be okay, but he started to get an upper hand over me. I was put into a situation where I had to end it fast, so I summoned something very large, something that I was sure would end the fight. I had it use a particularly strong attack but... I'm not sure why it had as much power at the time than it should have but... I accidentally made a part of Atlantis fall that day due to overestimating its strength.
Authorities were quickly on the scene, and I could only look on horror with what I'd done. A few of them were yelling death to me and threatened me with it, I was confused and in a panic, I ran away.

Goddammit, it's really hard for me to come up with a reason for why Yu would sink a part of Atlantis without some help. Maybe, a huge fire that needed to be cut off or something? No, that wouldn't make somebody cry "DIE YOU ASSHOLE"... dammit...
