The names of the elves are numbered. If you are looking for an animated work, and the names of the characters have numbers, then Dating Wars is definitely the answer you want. It can be said that the fairies in the war are all named after numbers (in fact, this should be said to be the strategy of the translation team), from the pilgrimage palace to Yatogami Tohka and even to Mayuri. It is this unique naming method that makes many people like this cartoon. Of course, I still say the same thing, children will make choices, from zero to 10 thousand!
The way to save the world is to kiss. In Japanese anime, ordinary high school students save the world in various ways. It's a bit strange to say that the way to save the world is to kiss like an engagement war. In fact, there are several steps before the hero kiss his sister. Just like "invite her to date, make her shy, grab her first kiss and bring her into the harem", the hero Shi Dao won her favor by dating the sisters of the elves, and finally sealed the spiritual strength of the elves by kissing, thus allowing them to enter the harem. Of course, this setting is due to the punching technology!
Elves are just women, and men have no good end. When watching this work, have you ever wondered why elves are all women? Not to mention this is the standard setting of harem animation. In fact, there are also male elves in the main part of the contract. And this elf is also very familiar to everyone. He is Ike, the villain of DEM society. In the volume 19, he successfully turned himself into an elf with the help of Guo's power, but he only lived less than a small chapter and died with Guo. The ending is quite tragic. From this angle, I can feel that the author doesn't like male elves. So I think the way to save the world in dating wars is to kiss. Elves only have women, and men have no good end. All elves have numbers in their names, which is an interesting setting.
