It would appear that "Attack on Titan" is earning itself a spot among most popular anime series of all time. That's because even years after its premiere (and the first manga volume), fans cannot get enough of the series.

Based on reviews, the fandom makes sense.

Although fans will have to wait for over a year before the "Attack on Titan" anime series returns, there's plenty of content available for consumption. The newest content are some special drawings of "Attack on Titan" characters that are given out to those who manage to see the "Attack on Titan: Crimson Bow and Arrow" compilation film in theaters.

Otaku Mode's Matt Schley had mostly positive things to say in his review of "Attack on Titan: Crimson Bow and Arrow."

"The upside of these cuts is ‘Crimson Bow and Arrow' isn't your standard mess-of-a-narrative compilation film," explained Schley. "Crimson Bow and Arrow basically accomplishes what it's meant to be do: keep the Titan ball rolling while Wit frantically pumps out more original content."

Unfortunately, until a North American release of the "Attack on Titan" compilation films are offered, only those in Japan will perhaps be able to judge Schley's opinion.

Nevertheless, the official "Attack on Titan" twitter is offering fans all over the world a chance to look at special artwork by the anime's character designer Kyouji Asano, with a special message from director Tetsuro Araki.

According to Crunchyroll, each person that attends a screening of "Attack on Titan: Crimson Bow and Arrow" receives the drawing on colored paper. The only catch is that the drawing is different every week. This means diehards who want each one will have to see the film once a week for well...until they run out of characters?

For the rest of the world, photos of the drawings, including the latest one of Mikasa, are available to view below. For next week's photo, follow @anime_shingeki on Twitter.
