Arima-chan as the captain of a pirate ship?!

I can't believe they took a part of the final episode of season 3 and focused so much on Arima-chan! I thought Akane-chan would be with her too, since it's a collaboration with Kao's Biore. I was completely wrong. This time, they've even deviated from the "supermarket girl" route.
But how will they collaborate on a ship? Will they put life-sized panels on the bridge and in the cabins? Or maybe sell merchandise like pennants? Well, that's all...

I was wrong about the April Fool's joke. | 西尾一朗's post
