Gate ~Jietai kanochi kakutatakeri Vol 1-10
Did a brisk read through of the tanks I bought since I've read them before. The manga definitely includes more things in it to build up the setting and the like over the anime. The creation of the city around the Gate was a bunch more pages, there are more minor and side characters, There's a side story that helps build Yao and Itami's general relationship a bit. Towards the end of Vol. 10, we're introduced to Hardy officially and the encounter with her gives the manga a slightly different direction. Hardy also confirms Tuka is into women too in their meeting, as she was looking for another lover since Rory turned her down. The manga also drops a few hints more strongly so it's nice to see them actually confirm it, heh.
A lot of the major story beats are in for sure but I'm enjoying the additional work they're doing to flesh it out. The 4-komas that are at the end of the volumes are really funny. The extra chapters that sneak in are great too. They had one showing how Worf, a wolfman that works security in town under Rory, and Meia, the catgirl that works the PX counter, spend their first paid vacation.
