Judgment

Make sure to buy Precision Press skill as soon as possible to have no trouble in the end game

The achivement is pretty self explaintory but If you find yourself late in the game with little SP and remaining 10k plus skills here is what you can do. (No, beating thugs 7000 times isn't the way)
When you unlock Quickstarter app there are different things you can fund, what we need are the Hug bombs. fund them starting with Alpha> Beta> Omega (this is the one we need)
I'll cost you 1.5 million to completly fund them (750K if you want to leave your console on for 10 hours and have the not so generous people fund the other 50%) and then you can buy Hug Bomb Explosion Omega from the convience stores which will give you 770 SP per bottle. if you use a Growth Extract before using one it'll go up to 847 SP. since each bottle of Omega is 140K you need to grind the Dice & Cube Long course which I won't get too much into about how to get the 6 Free pass vouchers or how to unlock courses but will explain the best and fastest way to get money (around 4 mil per run)

Short version:
You need to get into golden cube mode that give you bonus stage 2 times (3 if you're lucky and a golden enemy spawns in battle) then have all your things stolen by the purple cube, chase him down and get them back which in result gives you 2X of the items you already had

Detailed version:
- Go to Paradise VR and select Long Run standard rules
- hopefully you already have the Precision Press skill that will slow the dice for ideal results
- roll 5,6,2 dice (this will get you into golden cube mode, messing up the order will void it)
-finish the 3 stages then go to the golden cube that is present on the map, finish the 3 stages again and go to the purple cube to have your things stolen
- chase it down and beat it and you'll have twice as many items you had before then finish the run

Ideally we'll get around 3.8 - 4 mil per run on this method but with luck you can have the golden cube 3 times if you beat a golden enemy in battles but it isn't worth the trouble to look for it. you'll get 10 Hug Bombs Omega with 1.4millon which combined with Growth extract will net you 8470 SP. Use as many times needed
Hope this is helpful, cheers!
