This is the reward for being the kind of fan who actually bought the Blu-ray box, not the kind who streamed it and moved on. The Private Lesson bit was always a wink at the audience, and swapping out the stone-faced Kratos for Zelos flipping the lecture into his own personal victory lap is exactly the joke the franchise earned. It runs short, it's built entirely out of gag energy, and it exists to drop one announcement that had the fandom losing it in 2008. No plot, no stakes, just the cast breaking format to talk directly at you. If you know why Zelos volunteering to teach anything is funny, you're already grinning. Extras like this are why box sets used to matter.

Kratos-sensei's private lesson makes a comeback in this one-episode special, which was bundled with the Blu-ray box set of the Tales of Symphonia animation. Kratos is not around to teach this time, so Zelos steps in to run the lesson in his place, and he arrives with a special announcement to share. Fans of the Tales of Symphonia animation will find a short comedic extra with a fantasy backdrop.
