Context: Tsunashi Youta 十陽太 talks about tht doujinshi he has to make.
sessha kakeru anija kapu no orihon de gozaru!! 拙者×兄者カプのオリ本でござる!! [It] is an orihon with me × [my] older brother as couple!!
Note: using sessha 拙者 as first person pronoun and ending one's sentences with de gozaru でござる are things only samurai characters and otaku do, and this is no samurai.
Couples are described as A × B are typically ordered as seme × uke 攻め×受け, which means Youta's older brother would be the uke in his doujinshi.
komike mo chikai shi, ganbaraneba!! コミケも近いし頑張らねば!! The comiket is soon, too, so [I] have to work hard!!
orihon: {tokutei no sakuhin wo daizai to shita} niji-sousaku dewanaku, orijinaru no naiyou no hon (ikooru doujinshi). オリほん[おりほん]:特定の作品を題材とした2次創作ではなく、オリジナルの内容の本(=同人誌)。 orihon: not a derivative work [that] {makes as theme a certain work}, a book of original content (= doujinshi).
