Ostinato Apr 2026

Katsuro

Convinced he's awesome at everything, Katsuro's irrepressible overconfidence always gets him into trouble.

Mari

Life's too short to be bored for the bright, energetic Mari who enjoys playing tricks on her friends even more than on her foes.

Nobu

Gentle Nobu would rather talk his way out of trouble than fight. But he's always quick to apologise to anyone he knocks down.

Han

The self-styled 'Sensei of Cool', Han is calm in any situation. But constant one-upping with Katsuro is a headache for Sensei.
