A very good question, and we are currently investigating. Thanks for the heads up! --LP
No current plans for these, but as the first two are published by Shogakukan and Shueisha, who co-own Viz Media, it'd actually be up to them whether the series are licensed in English or not. -- LP
We're a company made up of a number of different people, but the majority of us enjoy yuri very much. We are absolutely a company of fans! It's no coincidence we're the largest publisher of yuri in North America, and we'll continue to share our love of it by bringing lots of great titles to our readers' bookshelves! -- LP
Hayate x Blade was moved to a different publisher in Japan, Shueisha, who co-owns Viz Media. Unfortunately that meant we couldn't license the series anymore. It would be up to them whether or not the series is continued to be published in North America now. --LP
No current plans for any of these titles, although Sweetness and Lightning is already being released both digitally and in print by Crunchyroll and Kodansha Comics. --LP
World War Blue is one of the very rare cases where a series sold too poorly for us to be able to license more volumes. If sales on prior volumes ever picks up, or there's renewed interest in the series (such as a new anime or game), we'd love to return to the title. --LP
The majority of those series are published by Shogakukan and Shueisha, who own Viz Media, so predominantly it would be up to them whether or not these series are licensed for release in North America. --LP
Absolutely we are! Volumes 1-4 of Nurse Hitomi's Monster Infirmary are available to purchase now, with volume 5 pre-ordering coming soon.

It's not typical for us to publish ongoing news about a book's production, so there's nothing to worry about in regards to Monster Girl Encyclopedia and it being 'quiet'. That said, the book is coming out on October 25th and will be well worth the wait! -- LP
We've never been 100% against light novels, but they require considerably more time and cost to publish, and manga continues to remain the more popular and requested medium. As with any series, we're open to just about anything we have access to, but it needs to be the right fit! --LP
