No, he was. But it was a 10-month to 3-year sentence IIRC, and he kept writing the LNs while serving it, too.

Edit: and apparently it was house arrest.

So he’s been out since around 2016-18 or something, no reason there won’t be more of the franchise.

The obstacle was that in japan his criminal record might have “disgraced” the series, but season 3 happening shows that didn’t remain an issue.
