It is a normal town which is not very different from the others, being its only characteristic being a port town. However, there are ruins in it that serve as a door to the demonic world.
20 years ago, on Morris Island, there was a great fire that it devastated all the town. Most of the inhabitants died, few survived. But later, some of the survivors testified that before the fire they were attacked by a horde of demons. But such a testimony did not come to be believed. Ernest, along with Tony and his mother were some of the survivors of the fire. However, both Tony and his mother were humiliated when they were accused of causing the fire, causing both to leave the town for these accusations.
Like many locations in Devil May Cry: The Animated Series, it is unknown exactly where Morris Island is located. However, it is known that you can get to the island by traveling by train, as Dante does once he travels from his city to the town back and forth.
Its only appearance is in the eighth episode "Once Upon a Time" from the series.
