A few months ago, Hilia followed clues to Deep Red Town and destroyed two bases of the Deep Sea Mutual Aid Association around it.
The latter base was dealt with by Rose, who resolved the self-destruct rune at the base and took the spiritual object collecting faith, a scale of an unknown fish.
After returning to school with this scale, Rose secretly arranged a reverse tracking array, successfully pinpointing the location of Sea God Ethel, who collects faith.
Because Hilia's strength was too low, Rose shelved plans to search for the Sea God.
Now, he feels very close to the Sea God, and after careful consideration, decides to let Hilia come and check the situation.
"From the sensed state, Ethel's situation doesn't look good. He might even be in a deep sleep, and although I haven't seen his divine fragments, his condition must be quite poor."
