An easy, safe and consistant strat. Your safe space is when your foot barely touches that piece of junk ( it's not super presice and there's plenty of time to adjust). His hitbox is kinda weird, but extremely generous. It is actually possible to kill that boss faster in JP by damage boosting (saves maybe like .2-.3 at best, so not worth it) or using bomb (not viable in chase/surrender, dont know about other categories)

You have to shoot him 3 times with C, after the first phase is done you need to go either to the left or right corner as soon as possible, take a hit and this will give you just enough I-frames to one-cycle him in the second phase. One C shot is enough for the first phase, but the one-cycle will not be as consistent.
