The Healer Who Was Banished From His Party, Is, in Fact, the Strongest

There was a Healer in a fighting team but the leader of that team kicked him out. He noticed that he was not contributing to all of ist teammates. After that, he went in search of new party members. After a long time, he found a cute martial arts girl. She knew it well and they had their party. Then he revealed that he is actually a DPS but never told that to his old team. He can only fight in the close combat form.
