I thought that too. Like, wtf woman, aren't you a several hundred (?) years old "divine" being with plenty of experience and lackeys? And some newcomer in her teens comes and steals your mail apparently without a sweat. That shit is just funny.
As for the goddess being an obvious cunt, keep that firmly in mind whenever
Sogou Ayaka (class pres) makes a decision. It will make you want to bang your head against a wall. (I've read the novel until latest translated chapter)
