我是怪兽我会瘦他是光芒他会燃
[wŏ shì guài shòu wŏ huì shòu tā shì guāng máng tā huì rán]
Breaking down into four parts - 'I am a monster, I will be thin; He is light, he will shine.' This complex name portrays contrasting personalities between oneself (monster, potentially dark side/thick-built that intends to improve/thin down) and another person or ideal self (bright/glowy figure who's expected to shine more).
