Seven Seas Entertainment has announced that it has licensed the To Love Ru (To Love-Ru -Trouble-) and To Love Ru: Darkness (To Love-Ru -Trouble- Darkness) manga. The company plans to release the series concurrently, with To Love Ru as 2-in-1 omnibus volumes and To Love Ru: Darkness as single volumes. The first volumes are scheduled for October 24, 2017 and October 31, 2017, respectively.
The story is described as:
Rito Yūki is your average high school student–awkward, shy, and hopeless when it comes to confessing his feelings to the girl of his dreams. But one day, an alien princess on the run suddenly appears in his bathtub. When Rito finds himself engaged to the beautiful Lala after a misunderstanding, he becomes embroiled in the chaos of extraterrestrial politics, rival alien suitors, and harem hilarity. The story continues in To Love Ru: Darkness, when Lala’s younger sister Momo begins her own machinations to marry Rito… but it can only happen if he is coronated as king of their interstellar empire, which would allow him to marry as many women as he wants.
Writer Saki Hasemi and artist Kentaro Yabuki’s To Love-Ru -Trouble- manga premiered in Shueisha’s Weekly Shonen Jump in 2006. The To Love-Ru -Trouble- Darkness manga, a sequel of the first To Love-Ru -Trouble- series, launched in Jump Square in 2010 and ended on March 4, 2017.
