我是你的奥特曼我是你的小怪兽
[wŏ shì nĭ de ào tè màn wŏ shì nĭ de xiăo guài shòu]
This can translate into 'I'm your Ultraman (a superhero in a popular Japanese series), I'm also your Monster.' The term is used playfully, signifying they have a double nature being protective (superhero) and maybe naughty (Monster).
