[Boys Love (Yaoi) : R18] Date A Live (デート・ア・ライブ)
I think it's a work with an extremely interesting concept.
The concept is ''what would happen if members of a secret organization dead seriously played a Love simulation video game''. Saying it like this probably makes it sound like I'm a no good adult, but when I heard that the person that was dead seriously playing the game was actually a member of a secret organization, I couldn't help but find it cute and adorable.
Besides that, the game plays in a world in which approximately 30 years earlier a big disaster happened that was caused by the appearance of mysterious life-forms and spirits of the death.
A high school student called Itsuka Shidou who is living together with his little sister meets a Spirit that has no hope for humanity. Thereupon Shidou finds out that he is a being that is capable of saving both the world and the Spirits.
The key is to date Spirits, and make them fall in love with him. It's not like the Spirits are causing the space quakes because they like it, so Shidou is very troubled as well. Rather than fighting and exterminating them, he will have to date them and make them fall in love with him.
To think that they are finally not satisfied just with dating humans in 2-D, but have extended their reach to spirits is a complicated feeling.
Personally, I prefer human girls to spirits... like Kotori, for instance! Little sisters with a cute gap are the best! Of course, it may just be that I have a Lotila complex. In addition to other things... (^ω^)
