Lets go with Senjutsuki Otoko then. American Mecha Plamo otaku Yuuya saves a girl from being bullied by a guy with long arms (and surprisingly white teeth) and a pro-wrestler looking guy in US. On transferring to Japan, he meets her again in class. On the advice of his otaku online friends he builds a Takemikazuchi Type-00F Imperial Royal Yellow custom and gives it to her, confessing to her. Thus the romance comedy of this high school otaku begins!
Spoiler for The Cast (No Relation to anime or game):
Cast:
Yuuya, mecha plamo otaku who is secretly fit because of his habit from running around the neighborhood when he screws up painting. Transfers from America to Japan following his father's job, mother remains in America due to pressure from work and grandfather's demands. "What otaku would turn down the chance to visit the holy land and get away from his mother", is his reasoning. Started online gaming recently as well, with surprisingly good scores.
Yui, Class Rep and Student Council President. A girl from a highly placed Japanese family, brought up to be a Yamato Nadeshiko. Absolutely serious about her responsibilities. Feels the first touch of romance while overseas attending a function when she got lost and was saved, and cannot forget the boy who rescued her from the drunks.
Yuuya's webpals on the Prominent Moon Shade blog forum:
Lowell, Yuuya's otaku high school friend in America, keeps in touch with him offering new designs. Heavy online gamer of RPGs.
Tarisa, a girl of unknown age from Nepal, who loves aircraft and model aircraft; has a short complex.
Cryska, a Russian who is socially inept. Joins the forum on the advice of her younger sister to learn to talk to people. Has frequent headaches when stressed, to the point of forgetting memories. Sometimes seems to have an alter personality. Does online gaming with her sister as the team Scarlet Twins.
Inia, her younger sister who is carefree; while she looks innocent on the outside, is actually a sharp reader of people, almost like she can read minds. Joins the forum thinking it was a teddy bear DYI thread because of the image of a brown bear. Stays on as she is actually a strong online gamer as well, teaming up with her sister as the other half of Scarlet twins.
Stella, an mangaka and illustrator who has a very precise eye; she acts motherly to everyone, giving advice to all. Joins the forum to exchange ideas about painting, and became a moderator soon after.
Giacosa, Italian playboy (self styled) who was roaming the boards for girls. Stays on when Tarisa insults him, and frequently lurks to argue with her. Frequently banned by Stella for posting lewd comments.
Latrova, Russian military wife who was bored. Chats with Yuuya often as he reminds her of her son who ran away from home. Gives Yuuya life advice that he needs. Occasionally inactive for long periods of time when her family is back.
Cui, girl from China, obsessed with martial arts and online gaming. Was in Yuuya's first game and saw him fragging multi-kills like a boss, using a unique drop. Found out that it was his first time playing, and started stalking him thereafter. Talks dirty with Yuuya online.
Sharon, Yuuya's ex from America. A normal girl who was in the same class as Yuuya in highschool, breaks up with Yuuya since he does not give her the attention she wants. Dates another classmate of his instead. Did online gaming casually, but normally does other girly things. Likes watching boys fight over her from a young age.
Leon, Yuuya's schoolmate in America highschool, and current boyfriend of Sharon. Dislikes Yuuya for his Otaku obsession, as being half Japanese as well, Leon was frequently considered the same as him, and was bullied unfairly as a result. Bloomed into hate in a certain event.
Maybe I should write something on this, if I ever get the time.
Well, save that script to your hard drive somewhere and turn it into a fanfic someday when you get the time.
