She first debuted in Episode 15, when Detective-GrapeJam-Looker was in a JAM! Thankfully, she showed up before Vaati The Wind Mage managed to ruin Persona 4 for everyone on one of his shitty, sub-par Twitch streams.
Ever since, Detective-GrapeJam-Looker has tried to claim her as one of his Facebook page's 'mascots'. However, Hex-StrawberryJam-Maniac beat him to it. So, he had to settle for the equally amazing Aigis...but he's still salty as fuck about it.
