I've noticed that too. In general, Japanese people will address people by their last name if they are anything but good friends.
I found this online:
Japanese, in general, has a lot of emphasis placed on politeness, and showing proper respect. It is possible to insult someone simply using the wrong form of address - which is why many anime series use this as a comedy device.
In general, first names are used in the following situations:
* Lovers, girlfriend/boyfriend, S.O - these are people who are close, and on an equal "level".
* Younger family members, like your little sister or brother. They, however, would address you as "older sister/brother".
* Close friends - we're talking "BFF" type of friends here.
Otherwise, it's very common to use people's last name - even if they're otherwise rather close. Switching from last name to first name can denote a large step forward in the relationship between those two characters in terms of familiarity. Think of the phrase "Mr. Thompson is my father's name. Just call me Joe." as a loose equivalent in English.
I think he did it to make Karino jealous...and he did. Also,Kuze calls kusakabe by his own name as way of manipulation,but kusakabe never called him by his first name, Karino is the King and Azusa is the target,it would be out of place (considering the game),also Karino wants to control Azusa and be above him...so it makes sense this way,for now of course XD
Wow you even search through the Kanji to find their name meaning! Indeed Karino & Azusa meaning are ironic. Maybe Yuuya mom gave him name Yuuya in hope that Yuuya will be great wealthy in the future. His mom said that he is the fastest at running and always had good grade. Don't know if yuuya still has good grade after high school
LOL I tried--but I don't know enough about kanji to really do that. I go by what I find on the Interent.
I think you are right--Azusa's mom wanted him to be wealthy and Karino's dad wanted him to be a government minister (so "fairness" and "justice" sounded good).
I've also been worried about Azusa's grades. It wouldn't be out of character for Karino to completely destroy Azusa's future even if it is for a game.
Well, I feel for people who still ship Karino and Asuza, and I admit that I started shipping him with Atsumu only because I think it would serve both semes right if they ukes got together and really turned the tables.
I guess right now I am more of an Azusa fan than I am any kind of a shipper. That's odd, because usually I ship characters the author isn't even thinking about having in a romance. I'm always looking for secret slash cues. This is a Yaoi full of MM sex, and all I can think about is how I want Azusa to do better.
Yup. I m totally azusa fans. I hope he has happy life inside & outside school.
I hope he can has a normal relationship with atsumu whether it's as good friend or as couple. I just hope azusa being happy.
Also, it will be good if Karino can be fall in love to azusa but azusa doesn't love him back and azusa live his life in better way than he is now. You got Serve karino!! Seme should get some psychological punishment.
Just for fun, I looked up the meaning of some names. I can’t decide whether they are ironic or not.
Kouhei (Karino): Justice, fairness and equality
Yuuya (Azusa): Wealthy one.
Atsumu: To gather, to congregate
Natsuki (Kuze): This is a pain in the butt, because it depends on the kanji. I started to go through the raws, but I simply do not have the skill to spot which kanji is his first name. Possibilities include: summer ____ [rare/life/hope/yearning…etc.], greens, moon, rich beautiful moon, and reminisce. Without knowing why, I’m guessing he’s hope and yearning.
Tatsumi: Another hard one. Could be imperial dragon or snake. Could be “accomplished”. Could be a lot of things.
I stopped there, because the names may not mean anything at all. I find it funny though.
