Yeon Yihwa/Abilities and Powers

Hwayeomsa (Flame User)
Flame User (화염사, Hwayeomsa): Yihwa is a fire user and claims her unrestrained flames are enough to cause the Rankers in her family trouble; Rak Wraithraiser has also mentioned that her flames are hotter than lava. She is also immune to Quaetro Blitz's flames. Initially she had trouble controlling her flames, as she fully admitted during her conversation with Akraptor, calling herself a 'defective product' because of it. However Yihwa's control got better over the next few years but she still had trouble with her accuracy and couldn't hit specific targets; despite this, she was later seen using her flames to knock out four opponents with a mini-explosion during a test. During the Development Tournament of the Workshop Battle, she managed to hit a member of Team Snake fairly accurately and also managed to hit a small target such as Medina from a far distance with Wangnan even implying that her training paid off. After the events of the Workshop Battle, Yihwa has gained more confidence in controlling her flames. After the timeskip, Yihwa has shown an impressive improvement on the control of her flames, being able to direct a large volume of flames to erupt from underneath Cassano. Her flames were initially a pinkish shade, tinted with violet, blue and sparks of white; however, in her most recent display, her flames appear a more traditional fire-like color with heavy black features. Furthermore, Yihwa is said to be from a very rare family even among the 10 Great Families.

Special Flame
During the attack of Karaka at the name hunt station to prevent Jyu Viole Grace from boarding the hell train, Yeon Yihwa, together with Androssi Zahard, Rak Wraithraiser and Hong Danhwa that at the time was being held hostages by Karaka, intended to distract the slayer with the wave shock of the ignition sword. They said they will sacrifice themselves in order to let Androssi escape with Bong Bong so that Baam would be able to board the hell train. And then they fell off from the bridge that seems to have endlessly height.

At the same time, Yuri Zahard launched her special attack: Rose Shower to distract Karaka from attacking Baam that was boarding the hell train, but it seems more likely that Yuri was intended to finish him at once and for all, rather than "distracting him" because of the massive scale and range of the Rose Shower. And in the end, Yihwa, Rak and Danhwa was ended up trapped on that full scale attack as well. The moment after that massive event, Rak was found out to survive that height fall and ended up inside the hidden floor because he got sucked into the small piece of the hidden floor mirror that fell out from Danhwa's pocket. However, Yihwa and Danwha was nowhere to be seen.

Later, it turned out that Yihwa and Danhwa didn't got sucked into the mirror like Rak but rather they were saved by Yuze, Urek Mazino's servant and was carried to the 43rd Floor not far from the entry to the Floor of Death. Yuze then explained to Danhwa, who just woke up from his faint, that it was all thank to the flame of the Yeon Family a.k.a Yihwa's Flame which was asleep within her body, that was activated and defended it's owner and made them survived the Rose Shower attack.

Notes and Notable Information

 * Yihwa's potential power cannot be be understimated. SIU wrote on his blogpost that When she gets her powers under control, she'll have an ability that will even put Koon Ran to shame.
 * It's still uknown if the flame power that Yihwa released during her fight with Angel is her kind of special flame, but it is capable to make her fly.
 * Not only that, the fact that Yihwa's special flame that was asleep within her body could defend and withstand against the Rose Shower, a special attack of Yuri Zahard, a Zahard's Princesses, and top 500 high ranker that was capable to terrorized Slayer Karaka to run for his life and also successfully made Kallavan to use the power of Essence of Bravery, perhaps could indicated that Yihwa's special flame is comparable to the top 500 high ranker in terms of power and technique.
