Yeon Yi-hwa is a D-Rank Regular from the Yeon Family who has been climbing the Tower with Jyu Viole Grace and Team Tangsooyook after the very beginning of season 2. She was known by some as the "Yeon Family's Flare".

When she was very young, Yi-hwa was praised for her incredible flames after immolating a person with them. Yi-hwa entered the Tower when she was 14 and passed the Second Floor with the highest scores. Afterwards, it took her only five years to reach the 20th Floor without anyone's help, including her family's. After failing many times by herself, she was later seen in the same test as Wang-nan, having burned him and the rest of her team, causing them both to fail the test. At some point in her history, she asked someone for help in trying to control her flames but was rebutted as she was a member of the Yeon Family.
