With the official ending of the IG, the former eight stars of the Moon gradually separated, each going to different heights.
Achilles was still a king who was very highly regarded on the Moon. He was not covered by Lear's accomplishments. After all, when the publicity angle was different, their focus would be different and hence, their results would not be the same too. Achilles, as the highly supported idol of Moon's youths, was definitely not lacking in this aspect, especially when he did indeed appear as part of the main force. However, for a period of time after the IG, Achilles also became very low-key. Of course, it was to decrease the amount of unwanted attention and focus on his studies and training. The IG was no more than a minor test, to allow him and his competitors to know more about each other's situation.
With growth, there would be changes. Friendship too, would not be stagnant. This was evident here on the 8 stars of the Moon.
