Training! The Black Room!! (特訓！ブラックルーム！！, Tokkun! Burakku Rūmu!!) is the tenth episode of Inazuma Eleven GO Galaxy series.
The match between Inazuma Japan and Shamshir has ended with Inazuma Japan winning. The team continues training as usual. Shindou Takuto has started to accept Inazuma Japan as shown when he compliments and gives advice to Tetsukado Shin. Manabe Jinichirou's parents visit him and tell him to give up soccer and continue studying, with Minaho Kazuto overhearing them. Later, Manabe and Minaho have a conversation together. They told each other about their backgrounds and then suddenly get into a fight. The next day, Kuroiwa Ryuusei takes everyone to the Black Room which allows them to train in a virtual city and different virtual dimensions for the past 3 days. Most of the team have started to think about winning FFIV2 even though they didn't need to. Later, their next opponent in semi-final is announced to be Thailand's representive, Mach Tiger.
- After Shindou gave an advice to Tetsukado, Tsurugi's uniform had the number 11, instead of 10.
[Tetsukado Shin] It's because it's impossible that we gotta do it!
