When Anri dials Mika at the end of the last episode of Durarara!! ×2 Ten (episode 24 of ×2), we see a shot of some of the contacts on her phone.

Anri's phone contacts

Entry #6, highlighted in the screenshot above, is someone named Tsutsukawa Azusa (筒川アズサ). As of this point in the story, am I supposed to know who that is? It's awfully difficult to keep track, what with DRRR having so many characters.

(Incidentally, the rest of that list is, in order: Akabayashi; Kadota; Karisawa; Shinra; Kida; Aoba; (Tsutsukawa); Togusa; Harima. Curiously, she only has 12 contacts in her phone.)

She is one of Karisawa's cosplayer friends, the girl that made Anri cosplay in one of the episodes.

Azurin and Reh-chan were amongst Karisawa’s fellow cosplayers, and were about the same age as Anri.

  • Ah, I remember her now. That was episode 10 of Ten when she's with Karisawa and they invite Anri to cosplay with them.

  • She is not a important character so it is actually fine for you to forget her.
