Just a heads up!
This weekend episode 4 will be airing in Japan on Fuji TV at 9 am and will be available to watch on Crunchyroll a few hours later after it has aired. It will be available on Crunchyroll from 3:30 am if you live in the UK.
You can see watch episode 1 to 3 for free without a premium account for Crunchyroll but you will need one for episode 4 if you want to watch it straight away.
