>>1642465>any reason he has gone the pushing the boundaries of fan service route?To begin, his artstyle has noticably improved over the series' run, and is much more condusive to ecchi content than before.
Second, Fairy Tail is now established as one of the top three manga in Japan, and Hiro is recognised as one of the most reliable manga-ka in the business. Basically, he has a lot more sway now to draw what he wants and is comfortable with.
And finally, the primary fanservice character has transitioned from Lucy (normal, modest girl that tends to wear trendy outfits) to Erza (nutty, covert pervert with a massive arsenal of revealing armours the plot has an excuse to make her wear). He usually had to contrive reasons for Lucy fanservice. With Erza, it's entirely unnecessary.
