Chapter 12: Hamel Fell into Darkness
In order to investigate the risen water levels in Resiam, Penensio asks Denka for help. Denka tells the El Search Party that causes were due to the disappearance of the Water Priestess Sasha, who controls the Water El that regulates the area's water, and the mechanisms in the Ancient Waterway being broken. After the El Search Party investigates the waterway, Denka speculates that somebody must have been tampering with the machines in the waterway. It is revealed that the Demon Scientist Conrad had been messing with the machines. After defeating Conrad, Denka notices the water levels beginning to return back to normal. However, Taranvash attacked the El Search Party while they were in the Waterway. Denka believes that the Holy Beast may have gone insane due to the Water Priestess being missing. After Taranvash was defeated, Denka asks the El Search Party to rearrange the reflectors scattered across the Ancient Waterway as he believed they are the key to unlocking the Guardian Stone's secrets.
While the El Search Party and Penensio continue to clear out the demons deeper in the Heart of the Ancient Waterway, Denka stays behind, trying to use the light cast from the reflectors to crack the Guardian Stone for its contents. Once the group returns to Denka, the Guardian Stone was soon stolen by Chloe. The El Search Party tracked her into the Heart of the Ancient Waterway and were able to retrieve the Guardian Stone back. With the Guardian Stone once again in Denka's possession, he places it in his device and activates it. His machine creates a recorded message from Helputt. Denka is surprised to see Helputt clad in black armor, unable to understand what the message was saying. With the help of the translation device, the group learns that Helputt had made a deal with the demons and has the Water Priestess captive. After hearing the message, Denka tells the group that they should seek out the Temple of Water.
Chapter 13: Secrets of the Temple
Penensio suspects that the Water Temple's location may be connected through the network of tunnels known as Magmanta's Cave, which Denka firmly agrees with. When the El Search Party reports back from the cave, Denka investigates their report and concludes that the demons are using charms to empower each other. Hearing from Daisy, Denka learns that the El Search Party were able to rescue the Red Knights from the spider's cocoons. Denka suggests the party should hurry as the spiders are likely to feed on the knights if they wait too long.
Once reaching the Temple of Frozen Water, Penensio meets with Denka to discuss the spirit Hagalaz, who was under control of the demons. Denka explains that Hagalaz was not the only one, but many spirits are being controlled by the demons. Denka aids in freeing the spirits from the demon's control, but he receives shocking news when Elsword informs him that the Priest Avalanche had been turned into a demon. Fearing that the demons had corrupted Avalanche beyond the point of return, Denka wished the El Search Party to free his soul.
Penensio once again went to Denka for assistance when confronted with Corrupted Red Knights in the Halls of Water. Denka discovers that the Red Knights had been corrupted in a very similar fashion to Helputt and there must be a place in the hall where the corruption is taking place. While investigating, they discover notes written in demon ink with a message written by Helputt detailing the events leading to his fall. Denka comforts Chung, who feels guilty from the message his father left behind. After the party discovers a secret path behind the main statue, Denka urges the El Search Party to move on and that time was of the essence.
Chapter 32: Recuperation
After the large El was restored in Elrianode and the Water Priestess Sasha having disappeared suddenly, Denka searched through the El wavelengths to see if he could discern what had happened. In his research he found a message in the El from Sasha herself. There she explains that she and the other El Priestesses are all together with the El Search Party.
Ecstatic to hear the news, Denka calls upon Horatio, a good friend of the Priests of Hamel, to discuss the news. In the middle of their discussion, Penensio arrives with similar news from Velder. The three talk about how Hamel has been getting better and Denka expresses great thanks towards the El Search Party for helping out and rooting out Rod Ross's plans.
After Penenio talked to Horatio about Rod Ross's current status, he asks about Helputt's situation. Denka responds that they have search all of Hamel for the fallen guardian but have found no signs of his whereabouts. He continues that he had learned from Sasha that the El Search Party do have their suspicions on where Helputt might be though.
