Kyouhei Sera  

Seri, 世良恭平

Kyohei sera is an etu forward with jersey number 20 who made it into the starting line-up when takeshi tatsumi became coach. his goal-scoring job as a forward and his dream to do a backflip after scoring the winning goal are important to him. when natsuki returned, sera was worried about keeping his position as the first choice striker due to the etu formation at that time requiring only one striker. he tried to prove himself by scoring a goal but sustained an injury and had to sit out subsequent games during which natsuki played and scored. katsura fujisawa observed from the sidelines and wondered if recent developments were a battle between sera, natsuki, and sakai for the lone striker position. however, tatsumi later switched to a two-striker format in the game against the osaka gunners.
