Binan Koukou Chikyuu Bouei-bu Eternal Love!

Years after the Battle Lovers last fought together, Wombat travels from the distant future to save Earth, aiming for 2015 but arriving in 2025 instead. He finds Yumoto Hakone still working at Kurotamayu, while the rest of the Earth Defense Club has long since scattered. Even Yumoto no longer knows where some of his old friends have gone.

Wombat's return means Earth needs them again, but gathering five friends after ten years is very different from calling heroes who only parted yesterday. Each of them has grown into a life beyond their school days. As a new danger approaches, they must rediscover the bond that once turned love into power and prove that time apart has not erased what made them a team.
