Based on a manga by Mitsunaga Yasunori, serialised in Monthly Shounen Sirius. Hiyorimi Hiro moves to a new city to live with his older sister, but dies before he can find her. He then awakens to a new life as a servant of a Princess of the Monster Realm, who just happens to be employing his sister. Monsters soon appear to attack or pester the princess since she is in line for the royal throne, and Hiro must protect her with his life (and repeated deaths).

OVA based on the Joker manga by artist Katsumi Michihara (道原かつみ) and writer Yuu Maki (麻城ゆう). Joker is a genetically engineered shape-and-gender-shifter, who created as part of a Special Police Task Force and fights crime of all kinds, but he/she also fits in a little romance around the edges.

The plot of this OVA is a rough adaptation of the first four chapters of the Guyver manga. It covers the same basic elements of these chapters; Genesis of the guyver, Fight with Vamore, Fight with Guyver 2 and the introduction of Guyver 3. Main differences are the exclusion of Tetsuro and his replacement by Mizuki, The replacement of Lisker with a female Agent "Valcuria", and thus a female Guyver 2. There is also a look at Sho's psychology of how he deals with his situation including a very harsh moment where his friends are assassinated in cold blood. One night, high school student Sho Fukamachi discovers a mysterious metal object. Then in a blinding flash of light, Sho finds that he has accidentally fused with the Guyver, a mecha of mysterious alien design. Now, to save his girlfriend, Mizuki Segawa, along with the entire world, Sho must become the Guyver to fight the Chronos Corporation and their biocreatures, called Zoanoids, who are hell-bent on world domination.

On a new day in the Kanto region, Satoshi gets invited by Professor Yukinari Ookido over to Professor Sakuragi's lab-opening ceremony in Vermillion City. During the ceremonial speech, Professor Sakuragi receives an alert of a possibly rare Pokémon appearing in Vermillion City's harbor, leading Satoshi and the other trainers to rush to the area in hopes of finding the mysterious Pokémon. At the harbor, they find Lugia—a Legendary Pokémon—engaged in combat with other trainers. Noticing the other trainers' tactics, Satoshi has his partner, Pikachu, strike Lugia with a Thunderbolt attack. Unfazed, Lugia flees, but not before Satoshi determinedly leaps onto its back. To Satoshi's surprise, he meets another boy, Gou, who leapt onto Lugia's back as well. The two ride on Lugia's back as it brings them along on a bizarre adventure across the seas. As it lets the two back on the ground, Satoshi and Gou bid their farewells to Lugia and return to Sakuragi Institute. Impressed by Gou's findings and Satoshi's insight taken during their encounter, Sakuragi requests for the duo to be his new research partners. And so the duo's journey begins, traveling across multiple regions to meet many new Pokémon—including ones that have the ability to Gigantamax!
