No, they're only the extra bosses following the game. Inazuma Eleven game pattern is that there are 2 game for the same season and each with different extra boss> Fire/Blizzard= Burn/Gazelle, Bomber/Spark= Desuta, Sein, Shine/Dark= Hakuryu/Shuu and everytime we play through wi-fi, we get a combination team of these 2. I doubt Sein and Desuta will return.
