There is no official release date for the twentieth volume of the dating war novel, but you can refer to the following information: Battle of the Date was a very popular novel series by Toko Amano. The story was about teenage girls who used special powers to date their dates and try to stop their relationship. The series had already released several novels, including the twentieth volume. However, in 2016, the author, Toko Amano, stated that she could not continue to release a new series of novels due to the limitations of her creative inspiration.
