Makes more sense if you have read the two mangas that come bethis so you can see the few chapters that introduce them and show the beginning of their relationship, especially the Kazuna one, which just has more of them in it.
A sniper man and his partner in crime. Love how the sniper is so manly and hairy and stuff, but the other guy is your usual yaoi hairless boy. Good dynamic.
Per reader, Takame: ⟫ Hana to Ryuu > Sessa Takuma > Kizuna > Gun and Heaven. 〚 3 years after Kizuna, the tashiro x j.b. couple settled down in some foreign country. 〛 Assassin couple returns. The many-faced, #half-japanese tashiro roy and his mentor and older lover j.b and their dangerous life together. Separate story, no appearance of prequel main cast. @CH. 6: shu hua cameo (the brat who chases j.b from kizuna). Kodaka sense's artwork has improved leaps and bounds in this volume. I was on a kizuna series binge and it's a nice treat to see how aside from sensei's artwork, you can clearly see the evolution in taste, fashion sense and architecture from sessa's 90's backdrop to GnH's latest 2016 fad.
