A collaboration between Pixiv and Reitaisai. Artists draw a high resolution image, following specific rules in the terms. Its dimensions also depend on the entry.

Each entry is submitted for a team. There are 8 teams: The main character team + 7 teams from the Touhou Project works, starting from EoSD to UFO.

The 8 teams compete against each other in a single-elimination tournament. Users submit entries for teams, and the team with more views at the end of a round will advance.

The contest is divided into 3 rounds, as follows:
First round: December 22nd - January 6th ---- Results published on January 11th
Semi-final: January 11th - January 21st ---- Results published on January 24th
Final: January 24th - February 7th ---- Results published on February 9th

Users may submit as many entries as they wish to. However, when two teams are competing against each other on a round, it is not possible for users to submit entries for both teams.

The tournament can be followed here. The number indicates the total number of views. The MVP (Most Valuable Player) is also displayed below the number of views. A user cannot be MVP more than once.
