OBJ Edge of Lightness's Description
"...Let me get this straight. Your team lost to Z7 in the combat drill 'cause you didn't graduate from a military school and Lil' Dodge wasn't your instructor?
Enough excuses, kid. I trained tons of raw recruits like you and I totally lost count on the number of losers who hamstring themselves by boo-hooing about their sad backstories.
Look at your face! Do you think I'm gonna give you a motivational story how a missing degree or diploma isn't that important? HAH! WRONG! I'm your friggin' instructor, not your pathetic shrink! I'm not going to make you feel good about your academic failures!
Since we mentioned degrees, then I gotta say — it's actually pretty important.
But if you're missing one, there are solutions to go about it.
I became an instructor after all. Guess how I did it?
WRONG AGAIN! I, Sato Kogo, never read a proper book in my life. In fact, I only learned how to write in Victorian thanks to courses offered aboard Dijiang. When I was your age, I was just a bummed out debt collector in Neo Tsukushi!
Wha? Don't you know what a debt collector is...? Ugh. Forget it. I'll put it simply. Hired muscle. That was my job.
So did that for about three or four years. I was either bruising people or getting bruised myself. As long as someone paid the creds, it didn't really matter to me.
I was in my twenties and I thought I'd be doing that for the rest of my life... I never expected something big to happen.
Oh yes... Stepped on a few toes. The wrong tail, actually. Not some cartel security firm, but an actual big shot oyabun.
Ugh. This is exactly why I kept telling you to pay attention to the surroundings when you fight. I learned it the very hard way, so at least take this from me.
Weather was great that day. I besieged that gambling den with two dozen bros from the organization. There were just around eight people on the other side and I thought it would be a cakewalk.
But those dudes fought like beasts in heat. Half of the lads were down in a heartbeat. I was out of ideas but I couldn't just leave my bros behind. So I came up with the clever idea of using the revolving doors...
How did I do it? Well, i simply undid the security latch and got it spinning... Anyways, I got two enemies down in an instant. Some of the bros started helping and we sent the rest of them packing.
There was one thing I miscalculated. The revolving door was connected to the one upstairs. Now that wouldn't sound like a thing but my boss suddenly got the bright idea of enjoying the spectacle. Suffice to say, his tail got caught — Boss man was also a Lupo and you know what they do when somebody messes with their tail.
What happened next? Geesh. Do I have to spell it out? I escaped to the frontiers before they gave me cement shoes! I slogged two years in trucking, four in janitorial work, and three in bounty hunting. My liver was dying on me and luck finally turned when I arrived at Endfield — Some old client wrote me a recommendation. Thank the Big Gas for that.
Alright. Your turn. Tell me about your plans on beating Z7 next time?"
