Nanatsu No Ma Ken Ga Shihai Suru 11 (Dengeki Bunko) [Light Novel]

[Machine Translation] Oliver and his friends are about to move up to the fourth grade. During the annual long vacation, they planned a trip back to the hometowns of their friends. They add Teresa and Marco to the members of Kenka-dan and begin a boat trip around the countries of the Union. While encountering Kimberly people on their journey, the group eventually arrives in Kati's home country, the Lake Country in the northern part of the Union. The vast forests and countless lakes, lake dragons living close to human settlements, and settlements of subhumans in their original form overwhelm the group. At the Aalto family's sojourn, the group learns of Kati's parents' past, which was intertwined with heresy. The journey continues, and the group visits Shera's parents, the MacFarlane family, an old family in the southern part of the Great British Magic Country. While being swept away by the dynamic personality of Sierra's mother, they are kept busy and meet an unusual centaur.
