Prologue: The Darkness Squirms (序章「闇の蠢動」 Joshō 'Yami no Shundō')
In the United States, China, Italy and Germany, people have started to become monsters and mass murders have occurred in recent months.
Surveillance cameras show a woman and two men dressed in black.
And now, the trio were in Japan. Seiji Hokuto, who followed them, was defeated by the mysterious black Ultraman.
Episode 1: Ritual of the Abyss (第１話 深淵の儀式 Dai ichi-wa Shin'en no Gishiki)
That was the woman in black clothes that Hokuto followed. She approaches a man at a restaurant in the bay area and whispers that in his ear, changing him into a monster.
Shinjiro and Moroboshi, who visited the bay area to investigate the cause of the mysterious "gravitational fluctuation phenomenon" (重力変動現象 Jūryoku Hendō Genshō), come across a sight like a "picture of Hell".
A man turned into a monster at an Italian restaurant, eating and killing people around him.
The monster is defeated by Moroboshi wearing the Seven suit, but returns to human form and mysteriously says "one man...not enough..."
Immediately afterwards, Shinjiro and Moroboshi, who followed the gravitational fluctuations, discovered the fallen Hokuto.
There, they met the three-colored Ultraman, in silver, red and purple. Shinjiro struggled against this mysterious Ultraman, who fought while changing the color and shape of his suit, before he escaped.
The three-colored Ultraman meets with a girl and shows his his youthful appearance. It is the young man Daigo.
He seems to be fighting alongside the girl Yuzare to prevent the ritual of breaking the seal of darkness...
Episode 2: Otherworldly Things (第２話 異界のモノたち Dai ni-wa Ikai no Mono-tachi)
Detectives Endo and Kurata, on the other hand, find that the man is a man named Kuriki, a serial killer who had killed 13 young women in the past, but Moroboshi of the SSSP halted their investigation there.
The trio in black robes look for "sacrifices" to perform a new ceremony because the "ceremony" was unsuccessfully completed due to Moroboshi's activities as Seven.
Yuzare, a young girl who has the power to see the future, heads for a new sacrifice with the youth Daigo to prevent rituals.
A new sacrifice, Kanae Iwatsubo, was in front of the Ultraman statue in the Giant of Light Memorial (SSSP Headquarters).
She worshiped Ultraman and killed her bullies and teachers, pretending it was "justice".
The trio in black robes were trying to use Kanae as their next "sacrifice". Yuzare and Daigo try to prevent them from doing so.
Furthermore, sensing gravitational anomalies, Moroboshi and Shinjiro arrive, and fight with the black-clothed men Darramb and Hudra.
Before Shinjiro and his colleagues managed to chase the escaping trio, the one who appeared in front of them was...a jet-black Ultraman!
Intense gravity fluctuations attack Shinjiro and others, but the three-colored Ultraman appeared before them.
Episode 3: Conditions of the Sacrifice (第３話 生贄の条件 Dai san-wa Ikenie no Jōken)
Episode 4: The Dark Pentagram (第４話 暗黒の五芒星 Dai yon-wa Ankoku no Gobōsei)
