A schoolboy and a schoolgirl arguing over what's real, aliens or spirits, sounds like an unlikely premise for a phenomenon. But that's Dan Da Dan for you: the anime built on proof, experiments and trust that grows with every episode. Now that trust-fuelled chaos is crossing over into Arena of Valor.

What we love: The character pairings do the heavy lifting here. Okarun's look comes to life as a skin for Billow, Jiji's style transfers over to Glidur and Momo gets her moment as a skin for Veera. Three heroes, three unmistakable Dan Da Dan identities.

Don’t miss: Grab the Dan Da Dan avatar early. And keep an eye out for the new minion decoration: a cat version of Turbo Granny, small but too charming to skip.

When it’s happening: The collaboration starts 26 July, with the full celebration running throughout August.
