It hasn't been too long since I finished my previous three recommendations, (Shuumatsu no Walkure, Shiga-Hime, and Death Mount Death Play), but I've decided that I found another three manga worth recommending, then I would do the same and surprisingly, it didn't take too long to accomplish that.
For the first of the trio, I'm going to talk about Spy x Family.
Set roughly somewhere between the late 60s and early 80s, much like the James Bond films that inspired it, this story follows a spy, code-named Twilight, who receives an assignment to create a family unit to infiltrate an elite school in order to get close to a heavily secured and paranoid terrorist. Unable to be provided by the agency due to lack of manpower, Twilight (going under the false name of Lloyd) first has to create his own family, beginning with adopting a child. Unbeknownst to him, the child he eventually adopts, a girl named Anya, happened to be a former test subject of a top-secret government experiment to harness psychic powers, making her an esper who can read minds. Quickly joining this impromptu family is Yor, a seemingly meek office lady who has her own secret; she's a professional assassin known as the Princess of Thorns. Only Anya is aware of all three of their true identities but finds the situation pretty cool.
Overall, it's a pretty amusing spy/esper/hitman comedy and I'm definitely looking forward to seeing how it progresses.
