What's the anime about a redhead whose friend uses magic?


I was watching an anime and closed out of it, and now can't get back to it.

Description of the anime: A redhead male lead whose friend learns magic to
find the killer of his sister, who was secretly the girlfriend of the redhead
male lead.

I was only 3 episodes in on Crunchyroll, so I can't describe it any more. Does
anyone know the name of this anime?




The anime you're talking about is **Zetsuen no Tempest** (or [**Blast of
Tempest**](http://www.crunchyroll.com/blast-of-tempest), as Crunchyroll
translates it).

It begins with TAKIGAWA Yoshino meeting his long-time friend FUWA Mahiro, who
has gained magic powers from KUSARIBE Hakaze (a magician stranded on an island
in the middle of nowhere) as part of a deal in which Hakaze will help Mahiro
figure out who killed his sister, FUWA Aika. Unbeknownst to Mahiro, Yoshino
and Aika were lovers. Drama unfolds thereafter.
