The right choice, Bisky is a menace and deserves respect

@NEONlights-lb8um

Urahara didn't just teach ichigo how to hollowfy, heck he didn't even teach him that. Urahara taught ichigo, a 15 year old kid how to fight ancient death gods with centuries of experience and magic spells within less than a week. And he's fought them with zero magic spells and official training. 
He's so good that once ichigo's opponents found out that he'd been trained by Urahara, they decided to fight with their full strength and yet, ichigo came out on top. 
Not to mention, his training device which helped ichigo obtain bankai within 3 days when it'd have taken elite noble clan soul reapers  at least 10 years to acquire and another 100 years to master. 
Yes, ichigo has natural talent. But gon and killua do as well. Urahara all the way

@nightlypiano41

Admittedly Yami's training style is just "lock in nephew" and it just so happens to work every time

@Kodex-TheFailed

I'd choose Kisuke Urahara because assuming I have some kind of abilities he'd be able to identify my power, potential, and a fast track to reach said potential to his abilities and knowledge. Plus he'd help me be creative

@tinfoilslacks3750

Urahara killed Ichigo, dumped Ichigo in a hole for 3 days, and said "heaven or hell, let's rock." 

Definition of "he's a loose canon but he gets results."

@spiderdude2099

Bisky really trained them up an enormous amount in an extremely short period of time.

@redpandamurphy

I'd still choose Korosensei because you forgot one crucial detail in this whole situation. You are not powered up like everyone else on this list. So, in terms of practicality, Korosensei would be best because he can tailor your training easily and help you get better within a couple of days. He taught the boys in Class 3-E how to bunt well in only a short time frame (not even like a week), and given that you aren't training to kill him, he can feel comfortable providing all your training that you may need, including stuff like sniping and assassination.

@Roninjumpanime

Yami just yells surpass your limits and spends majority of his days shitting and smoking

@ph3no

In this situation, it's Urahara all the way. 

Dude literally was able to take an ability that takes a decade (if not more) to learn and shorten it to less than a week. Not to mention how knowledgeable he is in different types of powers such as hollowfication and fullbring.

The only downside with Urahara is that he'll likely only explain half of what he's doing, if even that. But in a case where there's a war, he'll probably have backup plans on top of backup to insure victory and probably keep you alive.

Going with him.

@Dunsparce1265

Assuming you don't get powers, I'm going with korosensei.

@nerro5569

Man I'm taking urahara without doubt

@billards9285

Idk, biscuit's good but she also had A LOT of things going for her. A. Killua and Gon were already 1 in a million talents. Her first "training thing" was literally beat a nen enhanced serial killer with no help or advice. B. She had the help of greed island having built in training mechanics. Essentially designed to train Gon (she theorizes)  C. Wing already did a lot of the work 

Also the only reason Biscuit helped in the first place is because she hated seeing wasted talent. Her real goal was to ruin their friendship lmao.

@onuhrita5009

" he would probably kill me"😂 I don't know why that made me laugh so much

@Netherwolf6100

Bisky easily. The girl is a true natural talent when it comes to training people using basic and practical means. She doesn't hand out answers but doesn't leave you to fail about on your own. She won't coddle you in any way, but will not put your life in danger of losing it. Not to mention her abilities rejuvenate you so you can work harder for longer without destroying your body or needing far more time to rest, cutting your training down by more than half.

She's the GOAT.

@SpammytheHedgehog

Don't sleep on Biscuit.

@S1mpleThings

As a hardcore bleach fan, Kisuke’s training only worked because of who Ichigo is. He definitely knew how to maximize his potential but it’s not like he’s the reason Ichigo learned bankai in 3 days, it’s because Ichigo was literally destined to be the strongest in the verse

@Isthatthegrimreaper170

Plus her nen ability can divide resting times, which allows more time for getting in more reps
And if you’re somehow lucky enough to end up with Gon and Killua levels of potential you’re gonna be able to do anything

@Mercer87

I feel like Kisuke is a 50/50, either you end up stronger than ever before in the shortest time possible or you’ll be too dead for it to be your problem anymore 😅

@PENETRATOR1235

I am not a simp but I think biscuit is really good mentor.
