What can I say that hasn't been said about Smartphone Season 2. Is it pure harem isekai trash ? Yes, utterly. Is the MC completely bland and solely exists so the watcher can imprint on them for there own escape ? Yes, utterly. Is there a plot or engaging storyline ? Nope. Are the characters other than the MC at all interesting nope not really they just exist to fill a stereotype from loli to shy knight to lewd fairy.
Did I expect it this to get S2 nope, could I have spend my time watching anything else from the Spring 2023 season, yes. Will I watch a season 3 if we get one ? Yes absolutely ! Why cause not everything needs to be an AoT, Fullmetal etc. sometimes its nice to just watch some trash and switch your brain off.
