Outbreak Company: Moeru Shinryakusha Gaiden!

HER MAJESTY'S A PRETTY NICE GIRL Did we call Volume 18 "the final installment of Outbreak Company"? Oops! Boy, are our faces red. Anyway, the wormhole is closed, but that just means Shinichi and his friends can focus on their new lives in Eldant. For example, settling down with Myusel...until a certain absolute monarch declares she wants to marry our protagonist too! Shinichi isn't the only one with a relationship to work out, either—there might just be sparks between Hikaru and Elvia, but will this seed of love blossom into a true inter-time-linear otaku romantic saga?! Meanwhile, Minori is busy...well, being Minori, which can only mean...something. No matter what happens, one thing's for certain: for Shinichi, nothing ever quite goes according to keikaku!* (*That means plan.)
