Thank you to NetGalley and VIZ Media for the eARC in exchange for an honest review.
Tokyo Alien Bros. by Keigo Shinzō is a comedy sci-fi manga for mature audiences (it contains some depictions of explicit content). While the premise it explores--space aliens are among us scoping out Earth for future invasion--can go in many directions, the delivery here definitely embraces the weird. Fuyunosuke and Natsutaro Tanaka are alien brothers attempting to assimilate into contemporary Japanese society. Fuyunosuke is the competent, suave player, Natsutaro is the lame loser, but neither really knows what they're doing--the devil is in the details, so to speak. In Volume 2, their mission is clarified from the bumbling escapades of Volume 1: if Natsutaro can get a job and a human girlfriend, the invasion is a go. The catch--Natsutaro is a walking disaster, as evidenced by the end of Volume 1.
Some things to note about this series: it is definitely on the 'pure entertainment' side of the manga spectrum, and readers should be prepared for some male gazey ecchi/mature content. However, I do prefer this to other depictions of similar content because the fanservice is overlaid with a tone of curiosity (to a degree--this is still a story aimed primarily at cishet men). These bros genuinely do not know what it means to be human, so their quirks and questions, by extension, bring what we consider mundane and boring into a new light, somewhat like the 'Nacirema' perspective of anthropology/sociology research, but taken less seriously. I did also appreciate that this volume had more focus, explaining Natsutaro's point of view as he struggles to understand and assimilate more than his brother does. But if he can figure it out, why can't we? Overall, this manga is silly, kind of dumb and weird, but fun.
