- What is the "Tsuchinoko Break" raid battle? -
A "Tsuchinoko" is considered to be an unidentified mysterious animal, or a cryptid, in Japan.
In Japan, it is still known to be an illusive creature, and in some areas, there is even a reward for finding one.
As one of the kanji characters for "Friday" is used in the kanji characters for the creature "Tsuchinoko", we will hold the special Tsuchinoko raid battle on Fridays.
The Tsuchinoko will appear every Friday from 0:00 to 23:59 (JST) for only 24 hours.
Defeat the boss monster "Tsuchinoko King" for a chance to get the "▲Tsuchinoko King" Al Crysta and the "Tsuchinoko King Egg" that hatches a pet that you can raise on your Island.
