For those wondering if the series was cancelled, Comic Valkyrie does have an as-yet-untranslated chapter 41 up. Amahara just updates sporadically and prioritizes his other more successful projects.
He's explicitly holding up the elephant (xiang) piece in the picture. The pieces drawn by the artist resemble Xiangqi, or Chinese Chess, and not Shogi, which does not have a xiang. Amusingly, Xiangqi literally translates as "Elephant board game", so the elephant is doubly relevant. Incidentally...
IIRC there is not much left to translate. The manga got cancelled at Ch14. The LN is currently at 4 or 5 volumes but no one seems interested in translating that to English.
