Anime like another world with my smartphone

@unknownmat In terms of tone, Vols 1-3 fairly closely match the anime. As in it's a lighthearted, walk-the-earth, adventure kind of story. Season one of the anime did a fairly fine job at capturing that feeling, but it definitely retained a fraction of the short stories/arcs told in those volumes.

As for season two, while it's covered some incidental stories, it has pretty much focused on the events surrounding the remaining three girls becoming Touya's fiancés in a pretty liberal retelling. So it's probably better just to think of it as an alternate timeline.

Comparing Smartphone to Death March, if Smartphone represents junk food (e.g., lighthearted, easy lane, antagonists exist purely as an outlet for MC's violence, all highs no lows, etc.) I'd say Death March can at least be recognized as a meal (e.g., firmly idealistic, has lows but always resolves to a supposed 'best' ending, MC generally has a mature outlook, etc.).

If you're looking for any complexity, I'd say Smartphone isn't a series that has it in any meaningful quantity. The overarching pattern of series is Touya goes somewhere (once he's acquired all the fiancés, occasionally one or two join him), makes friends
