The Eminence in Shadow, Vol. 9 (manga) by Daisuke Aizawa

A troubled wind is blowing—Mitsugoshi’s new innovations have put them in the sights of entrenched business interests, and the filthy quagmire of shady underworld schemes is escalating to all-out economic warfare! Naturally, there’s no way Cid would ignore something that cool-sounding! If it looks like the girls are getting in over their heads, he’ll just have to step in and betray them to save the day—not as mild-mannered Cid or the grim and mysterious Shadow, but as Super Elite Agent John Smith, he who destroys all and rebuilds it anew…!
