A 1989 OVA about a boy saving the world from the evil scientist.

In June 2044, the Robotech Expeditionary Force (REF) fleet gathers at Moon Base ALUCE for its final attempt to drive the alien Invid from the Earth. This time, the REF has important technological advantages thanks to the help of the Sentinel races; the Karbarrans provided the industrial resources to construct this armada, while a secretive and highly advanced cybernetic race known as the Haydonites have provided advanced technology including Shadow devices, which make REF ships invisible to Invid sensors, and Syncro-Cannons, which are significantly more powerful than the REF's earlier weapons. The REF fleet is led by newly completed SDF-4 Izumo, a Super Dimensional Fortress over 1.3 km (0.8 miles) long under the command of General Gunther Reinhardt.

Reborn for the sake of a previous life. Reborn for the sake of martial arts. Chu Yang was under attack for the sake of the Jiu Jie Sword. Our hero was trapped and outnumbered by plunderers. Unexpectedly, between life and death, he was brought back 16 years in the past. Is this fate, or a coincidence? Will Chu Yang be able to change the past?

In her house, Mei Onigami discovers a strange round creature that only says "chimi." Her sisters, Mutsumi and Hazuki, agree to let the being stay with them until its owner comes to claim it. However, as soon as one of them utters the word "hell," more creatures show up until there are 12 in total. The sisters think nothing of this until the critters create a portal that summons an envoy from Hell. Jabberwock the Eighth, a horned and fanged man covered in fur, has come to unleash a living hell on earth under orders from his boss. However, when living in the human realm proves to be challenging, the Onigami sisters allow him to stay with them. They also take in his "Chimimoryo spirits"—the round demons that preceded his arrival. Called Jigoku-san by the Onigami sisters, this messenger from Hell has a lot of work cut out for him if he wants to take over the world. But before that, he will have to survive the everyday hells of human life.
