Pretty nice guide. It's fairly close to what I do, although dead wrong in a few areas (such as, using Hottie Regen puts you back half a day in terms of speed, so using it is utterly idiotic).
Toss Flipper into your team. Do the quests to get Stalkergirl, Meatballs, and Shorty. Run Reaper until you get Robogirl and TicTac. Get your Soul Candy. Run missions with a team of them until you hit Level 12. Go Chunin. You should be able to do all this the first day you loop.
As a Chunin, go for important allies you may have missed. These include Pinky, Billy, and Red Rover from Gen-specific D-Ranks. If you're a Red Eye (And why wouldn't you be if you're going for speed?) be on the lookout for the missions that teach Dragon Flame and Mind-Body Switch jutsus. otherwise, be on the lookout for Lil Ro and Emosuke. get Terri from the C-Rank Tai, and be on the lookout for Bruce Sr for future Jonin. Terri, meatballs, and Rover all level on Gen C-Ranks. Spot does too, if you get him along the way. Again, Red Eye and its village upgrade are immensly helpful here. Hopefully, Rover will drop some dog treats along the way. Get Spot if you can, his EDUT jutsu, and a couple of spare treats. Focus on Gen until it hits Level 13. This time, look for K.Y. along the way for future Jonin. Spec Jo time. Timmy Missions go fast with Timmy + Stalkergirl. Toss in Rover if you still need treats. You've levelled 3 allies? welcome to Spec Jo. With a few nice Stamina bonuses, you can do all this in the second day that you loop.
Jonin grind takes a bit longer. First real step will be to level Billy, Pinky, and Stalkergirl. Work on Pinky's tai mission first to have 2 allies that give back stamina. Look for Rover's Mom if you still need Jonin allies. While searching for Billy's gen mission, keep an eye out for Annie's mission. If you still need Golden Shinies, you'll want her. She can level while searching for Stalkergirl's nin mission and also Smokey, again if you still need jonin allies. While on a levelling kick, stop by Reaper Tai to level up Timmy. Level 41 means Jonin time. A good day with stam bonuses makes 300K not that hard. Brute force what you can, specific jutsu what you can't. Hopefully, you still have a couple of team changes to complete the exam. This could take a couple of days, but you could be only on Day 3 by the time you make Jonin.
Jonin now, yay, but that means griiiind. Take this time to get Trade, and work your way up to Note. Note Rushes are invaluable, as is Anon's jutsu. We need a couple of things from Reaper now, like Strawberry. Look for him in Reaper Tai. Use him to get the Captain's Jacket. Like Annie2 before him, Mister Tea is optional but very useful when going for Golden Shinies. But he can be tricky if you can't afford the allies and jutsu needed to auto-pass his mission, and can't successfully brute force it. Either way, it's the home stretch. Focus on whatever stat is higher, and do A-ranks specific to that stat. Timmy2 + Pinky2 + Stalkergirl2 is the way to go. Use Obsessive Insight on every single mission (some enhancing may be required) and grind, grind, grind that stat up until you can loop.
What, you wanna go Sannin? Sannin is a sucker's bet for speed looping. Generally, by the time you just have even enough levels to go for it, you'll be ready or past ready to loop. Then there's the 150K you need to spend to get The Rack. Not worth it.
OPTIONAL: Once you get to about Level 48 or so, you can start thinking about Golden Shinies. Most Jonin immediately go for Sannin once they think they can get it. But, with that 1 Million Ranking, you're basically a lock for Top 3 Jonin. When you decide to go for it, make a team of Annie2 + MIster Tea + either Pinky2 or Stalkergirl 2. Get a Note Rush, get the Arena Favorite if you can. Chug any Silver Elixirs you can. If you can get over 1 Mil, you're Top 3, and can go get your Shiny.
"++Sannin
There is no Reason to Go Sanin when Speed Looping, as it cost 150,000 ryo to get Sanin as you will need The Rack"
This makes no sense, as just above it you tell people to have The Rack in their daily party.
Well, the whole idea of a Rack + Anon + LisaLisa party doesn't make any sort of sense to me.
Put LisaLisa Lvl 2 in your party. If Stalkergirl, Pinky, or Emosuke is your 'Valentine' AND you have their S-Rank Drop, put them in the party too. Fill out the rest of your party with either LisaLisa if you don't have her Level 2 form, Pinky/Emosuke/Stalkergirl if you have their S-Rank drop but not their Valentine, or Mr Sandman if you have his Valentine.
You can get up to 100 Stamina over dayroll this way.
Does anyone else believe that Out on Top should be taken out of this guide? It serves no purpose when speedlooping because you grind a single stat and dont care about the rest. While your stat you are grinding requires 120K AP to level up, one of the other two stats that you dont care about may only need 40K AP and you dont really care that the minor stat leveled up. Please respond.
I still don't under stand why you would get Captain's Jacket.
TO get Captain's Jacket, you need to put out at less 80 stem. 15 in "The Path Of The Reaper" (half of 30). 10 for Strawberry, and and 50 for "The Reaper Council". I have +188% AP without the Jacket, and I been looping every 3-5 days.
With a little good luck It take 1 good day to go from Loop to Sp. Jonin. 1 day to get from Sp. Jonin to Jonin. And 1-3 days to get looped from Jonin.
I got from S6 to S9 in 10 days.
EDIT: looping to S10 has taking me 5 days
So the Jacket would only be good at higher loops.
And you forgot to add Late-Night Snack. Having that, and the Sp. Jonin upgrade (academy?) will cut your exp needed for jonin by 3, so you'd need a measly 100k exp. Quite easy to do even with only a fair amount of stamina. So no real reason to get Mister Tea, for the ranking…And as it's been said, it takes a fair bit of stamina to get the captain's jacket, even with smokes, so I'd say to avoid the reaper area entirely, to be honest.
