A story about a 212cm military otaku with "Sensha Otoko" as his handle name. Despite his huge and imposing appearance, he is actually very shy, and thus had no girlfriends. One day, he saves a teenage girl from being harassed and promptly fell in love with the girl. However, because he has no experience in romance, he consults his otaku friends on the web-board Eirei Throne-Channel for advice. This is the beginning of a True Tank Story.
