A Court Magician, Who Was Focused On Supportive Magic Because His Allies Were Too Weak, Aims To Become The Strongest After Being Banished

Story:

Alek Yugret was once part of the strongest party that conquered 68 floors of the capital's dungeon, a record that hasn't been broken by anyone else since. While working as a court wizard, he was kicked out from the prince's adventuring party due to being only able to use support magic and was fired from his position as court wizard. He then decides to form a new adventuring party with the cute girl who was part of his adventuring party when they were students.
