loke arc is really a good example of how peak the early fairy tail writing was. in the span of (2) episodes, loke's entire backstory is revealed, both his and lucy's characters are developed, we get new lore about celestial magic, fun filler scenes between the main cast and a good set-up for the tower of heaven arc. it's probably the shortest arc in the series, but remains an all-time fave because of this

natsu would ignite himself until he became one of the stars in the sky to get lucy to look at him

However in dragon slayers, this causes extreme motion sickness! Biology babeyy
