Eduard Events & Ending at English (from the game : Meine Liebe Tanbi Musou)

Hi, I currently playing the game & I upload all the scenes & ending with Eduard that I got. The game is originally Japanese but I translated it to English with help from guide. The heroine is Erika of course (from the manga) but I named her Kaho (inspired from la Corda haha ^^) cuz the game only allowed 4 characters for the name of heroine ^^;
