You must accept the “vs.-player battle” quest on the board named ”超ログレス大戦-予選-“ in Japanese and win the battle point below, so you can get that clothes you want as a reward.

over 18000 pts: tops, over 25000 pts: bottoms and over 100000 pts: shoes.

You can accept this battle quest only one hour from 21:00 to 22:00 everyday.
But be careful! This schedule is showed in Japan Standerd Time (UTC+9).
So you must adjust it to the timezone of the place you live in.

I hope you win the enough amount of the battle point to get all of those clothes!
