"The Day of Sagittarius"Spoiler Warning!! [+/-] Show/Hide Synopsis... Hoping to reclaim the computer Haruhi extorted from the Computer Research Society earlier in the year, the Society challenges the SOS Brigade to a computer game they created for the cultural festival entitled "The Day of Sagittarius III". The stakes of the match are as such: If the SOS Brigade wins, they receive four brand-new laptops; if the Society wins, then they get the computer back that Haruhi stole from them. Haruhi accepts their challenge, but soon finds out that playing the game is much harder than she thought.
