You decide to start training your quirk and body

You begin training your quirk and body and after 3 months you have made good progress. You have developed your muscles quite and are now able to use the light cloak for 1 minute and now your light beams can travel at 15% the speed of light. Also your spheres of light can now heal both minor and major injuries. However you can't use the cloak of darkness but can use weapons of darkness though it is difficult to maintain them. During your latest training session however you try to combine your light and darkness and come up with unexpected results the two once in contact fuse together into some strange cosmic-colored energy only to explode soon after in a violent explosion. You spend the next 9 months training to use that energy and afterwards you body becomes quite developed and your control over your quirk has improved to insane levels. Your light beams can now travel at 30% the speed of light, you can now create large spheres of light which unlike before covered only 200 feet they now cover 500 feet. Your skills in using your darkness have improved a lot as well now you can create a dozen weapons of darkness and can even create a while poor replica a replica nonetheless of a blackhole which while can't atomize things can still crush people and objects with gravity nearly 500x earth's gravity it also pulls thing's in. One of your greatest feats has been your progress with the cloaks of light and darkness which you can both use and have improved them to up to 7 minutes at a time. You can now use the newly named cosmic energy to create beams of cosmic rays which both have the searing heat of your light beams and crushing gravity of your dark beams. You can also create constructs of cosmic energy however you can only use three at any given time, however they are much stronger and much more powerful than your darkness based ones. You have yet to find out how to make a cosmic cloak. While wondering down an alley way thinking how to make a cosmic cloak, given all your attempts to have failed, your sensory field pings a sudden spike in fear from a young boy. The cause of which being some sort of sentient sludge you also notice the man chasing him through the sewer which makes you smile, you immediately appear before the young green haired boy and blast the sludge monster with a weak cosmic ray. Knocking him out due to its unique properties, after which All Might arrives and start talking.
