Holy Roman Empire

神聖ローマ

Germania’s grandson, who was in love with Italy (then Chibitalia) because he believed she was a girl.
For a time, he lived with Austria, Hungary, and Italy. It was during this period that he decided to try to persuade Italy to form a new Roman Empire with him. Italy, however, refused, stating that he did not want Holy Rome to end up beaten and fatally wounded like his grandfather. After entering the Thirty Years' War, he disappeared and is believed to have died. Previously, he had said his goodbyes to Italy, who gave him his panties (changed to a deck brush in the anime adaptation) as a memento. The two never met again, but Hidekaz Himaruya promised a happy ending to their story (which has not yet been revealed).
Holy Rome was quite strong, but had an extremely weak constitution. His love for Italy was so intense that his empire crumbled and he did not even care. He was depicted as short-tempered, but kind when he chose to be. Regarding skills, he lacked any artistic ability, but was very smart (apparently, Austria had him studying constantly).
According to Hidekaz Himaruya, his height (as well as Chibitalia’s height) was revealed to be 7 apples tall (about 90cm or 3’0”).
In the English dubbed version of the anime, he was given an Italian accent, which, as fans pointed out, was historically inaccurate since he was of Germanic descent. In reality, either would suffice considering that the Holy Roman Empire comprised several countries and territories of different ethnic backgrounds, so no single official language was ever recognized.
