Dual! Parallel Runrun Monogatari Special

Both Male Leads are sent to another world/dimension Both are really strong in the new world/dimension Both are Harem Both fight with Mechs Both are kind hearted and want to protect Kenshi is just GodMode in this no-1 can touch him. Basically Kenshi is sent to another world to deal with Gaia a Demon shield, but he doesnt know this :3. I suspect it was one of the 3 Goddess. This Anime is a must watch, its related to the Tenchi series, but its Tenchis brother that stars in it. No other Tenchi series characters are seen. The Eps are about 50min long minus intro and credits so like 40-45min
