sighs in reality Ayato is the oldest triplet yet he is the fifth son and Laito is the youngest triplet and the third son in the Sakamaki Family. Anyway I am a role player and fan fiction writer also I write poems for Diabolik Lovers as well.
The birth order doesn't matter for the triplets seeing that there is an old Japanese that states that the first born in a set of twins/triplets is the youngest and the last born in a set of twins/triplets is the oldest.
Ok did not know that but there are several places outside of wiki I get my information from plus the people I get it from have played the games not saying those who run this wiki haven't but some of them have actually read the character books and other information released in Japanese Magazines before the game(s) were released in Japan. Some people also research different things related to specific elements to the characters in general.
whenever you want I will role play with you. Message me here or if you have facebook check out my admin page http://facebook.com/AdminDarkPrincess tumblr http://redyumacosplayrp.tumblr or twitter http://twitter.com/redyumacosplay. I role play as Laito Shū Kō/Kou Yūma, and Azusa at the moment but I will be adding Carla and Shin in as well.
Tumblr is where I get most of my translations for the games since AkuiChanserā translates them. She is working on Vandead Carnival and I think she will be finishing Kanato and Reiji's routes from More Blood as well then starting on Dark Fate. I've met people on youtube who have played the games as well. I also know a few other translators who use wordpress and livejournal as well.
