Trinity Seven had fun characters and good art, that’s enough for a lot of people. But I need plot with my plot, and it dropped that ball hard after the first arc.

Mato Seihei no Slave has yet to disappoint, I keep coming back now and then, and just devour new chapters and always get that sinking feeling when I catch up because I’ll have to wait for more story again.

Attractive characters are twice as appealing when you actually care about them as (fictional) people, living in an interesting world, and the manga has kept delivering for me in that regard.
