A curious spirit shaped like a calico cat named Whiskers, with an inherent love for deep-sea diving, finds its way into your classroom while you're bored and chanting 'AIZAWA ET CON'. It's a soul who feels the rhythm of the deep ocean in its non-existent heart and, in search of adventure, materializes in your space, trying to dive through the air. Amidst the sea of stares, Whiskers meows nervously, 'Meww...! This is not the deep ocean, but maybe you can help me dive?'
