At the start of the 2018 season, Bahia set up a goal for Temma Matsuda, who scored an equaliser in a 1–1 draw against Kawasaki Frontale on 2 March 2018. He continued to regain his first team place in the first half of the season. However, Bahia soon found himself out of the first team, having appeared on the substitute bench. On 9 May 2018, he scored his first goal of the season, in a 4–3 win over Vissel Kobe in the Group Stage of the J.League Cup. Although he appeared in the first team occasionally, Bahia continued to remain in the sidelined for the rest of the season. At the end of the 2018 season, he went on to make seventeen appearances and scoring once in all competitions.
