IDK if that kite is Sonic3 but it has 55 cells instead of Sonic2 which has 49. Having more cells is the "easiest" way to try to improve performance of a high aspect kite.
Air intakes have four cells in between them. I struggled a bit to find out how to design it somehow appropriately, how it is done for example in R1V3 is much simpler - if not simply better. Interesting to see how bridle and inner structures have been done in this kite.
BTW I forgot the miniribs in design, all Sonics have them (I'm not sure first version though). AR in the picture below might be a bit lower, it is 7.2. These kind of things are very easy to add or adjust in design phase. But it is completely different thing is how useful very high AR's are in practice. MIniribs are beneficial even though they add weight and complexity (costs) of kite.
No doubt it is an excellent kite for its genre, it is a Flysurfer kite. Sonic2 is a very good kite already.
