Peter Grill to Kenja no Jikan: Super Extra

Peter Grill is still the strongest man in the world, and that reputation continues making him a target for women interested in producing exceptionally powerful children. This time, however, his life is crowded with more than attempts to escape admirers. He must help deal with a goblin incursion, take part in negotiations with dwarves, and survive the watchful presence of a sister who knows his weaknesses and refuses to let him disgrace the family. Meanwhile, the women pursuing him are not backing down, and new rivalries only make the situation worse. Between heroic responsibilities, his engagement to Luvelia, and disasters largely of his own making, Peter needs far more willpower than physical strength.
