I wanted to ask where I can watch Date a live 2 1 can I watch Netflix and 2 can Wakanim?

But I didn't find 2 anywhere (please only legal sites).

Hay on Anime.tube you can still watch all 3rd seasons. Nothing happens on this site, it's free and secure. But you have to hurry to watch the seasons, because the anime has been licensed, it may be deleted from the site in the near future.
