Take a deep breath, and an RPG reference for the full name of this anime is “My Isekai Life: I Gained a Second Character Class and Became the Strongest Sage in the World!”
I don’t understand a word of the trailer, which is the third for the series, but I am pretty impressed with it. It’s high octane and makes bold use of split-screen.
IMDB tells me that the friendly wolf we see in the trailer is called “Proud Wolf”; at least, I assume the wolf is Proud Wolf. Equally, the be-leafed woman who appears briefly is likely to be Dryad.
The series is due in Japan on the 4th of July and launches with an hour-long opening.
As the name makes clear, this is Isekai, so someone from our world ends up in another. In this case, Yuji Sano gets home from a thankless and gruelling job to find a message on this computer that summons him into a fantasy world.
Sano becomes a slime monster tamer before unlocking that Isekai classic, the sage.
In addition to this latest trailer, we’ve also a new poster for the show, and in it, the slimes seem fair happier than the demon.
