在这部三次元女友 第一季动画片中,高中三年级的筒井光是所谓的御宅族少年。
只要有游戏或动画里的二次元女生的话，感觉就能独自一人生活了……。
但，他突然被超绝3D（现实）美少女·五十岚色叶告白，并开始和她交往！
在被奔放的色叶玩弄于股掌之间的同时，筒井逐渐爱上了她……。
Hikaru Tsutsui is a quiet, unassuming high school student who forsakes the company of his classmates to spend his time reading manga, playing video games, and watching anime. Hikaru is perfectly content to dwell in his 2D world, until one day he's assigned to clean the school pool with the beautiful Iroha Ikarashi, and she confesses her feelings to him. Will Iroha's affection draw Hikaru out of his shell?
《3D彼女》哈？你说这充满男性向气息的动画原作…竟然是少女漫？！真的假的？。你管这玩意儿叫少女漫？编剧，我想看甜甜的恋爱！不是纠结的三角恋和胃疼白给！。适合内心温柔的人看。这ppt竟然有点甜？？？。本番制作各个方面都很糟糕，但却值得一看。啊筒，我啊，这里有个小怪物。
