The Battle Frontier is a whole new area introduced in Kiroe, which is heavily based off of the Battle Frontier in Hoenn.
After the Kiroe league, trainers can get the S.S Britana ticket from the creator of the Battle Frontier, Brian. The rules in each of the facilities also seem to be different than those in Hoenn - for one, one may challenge the head of the facility immediately, without having to win a series of battles first.
After winning at each of the Battle Frontier locations, the trainer can receive silver and gold Battle Frontier badges, known as Symbols, from the location's Leader, collectively known as the Frontier Brains. When the trainer defeats all of the leaders, the trainer receives an extra star added to the Trainer's Card and a Battle Frontier plate, symbolizing their completion of the Battle Frontier.
The Battle Frontier is located in the ocean in the southeast of the Kiroe Islands region. It was established by a man named Brian who is said to seek specially talented Trainers from across the Kiroe Islands region. During the course of the game, the main character will come across Brian who is supposedly observing him/her as he/she defeats the various gym leaders around Kiroe. Once the player conquers the Pokemon League, he or she receives a ferry pass and enters the facility.
