Chakra of course.

"Kirei, you are a genius when it comes to fuinjutsu. However Iruka tells me you struggle with the basics, especially creating chakra. So I'll be teaching you a chakra exercise used by chunin. I think it will help you alot." Rei gives you a smug smirk. You scowl. "Fine."

Anko looks at her next. "Rei, Iruka told me you had the potential to be 1 of the if not his best student. However he wanted you to train with lighter armor and work up to the heavy armor your wearing. Thanks to this, you have diminished your growth when it comes to 2 of the most important tools of a ninja. Speed and stealth. Lack of talent is 1 thing but stubbornness I cannot tolerate. You will train as I tell you, do you understand."

Now your the 1 smiling smugly. Rei protest. "But this is the first hokages armor and my inheritance. I'll always be using it in battle so there's no point in me training without it." Anko sighs. "Your lack of speed and stealth isn't your biggest weakness. It's your belief you are always in the right. I'll let you wear that armor in battle but your not ready for it yet. Please train without it until you are."

Rei pauses for a moment. "The summoning jutsu." Anko tilts her head. "What?" Rei explains. "My dad is trapped at Mount Myoboku. The land of the toads. If I can learn the summoning jutsu, I can learn the reverse summoning jutsu and I can meet him. Teach me the summoning jutsu and I'll agree to train without my armor."

Anko nods. "I know the summoning jutsu but I have a contract with the snakes, not the toads. I'll ask the Hokage to get us a toad summoning scroll. Until he can get 1 for you, you will train speed and stealth with me. Do you understand?" Rei nods.

Anko nods. "Good. Yume, Iruka told me you are proficient in every skill and jutsu expected of a freshly graduated genin. Not only that, during my test you worked with Rei without complaint and instinctively knew how to best work with others with your skill list. As such you will be my second in command." Yume blushes. "Oh, I've never been complimented so much before."

Anko continues. "He also told me you don't know any D rank or higher jutsu and don't really have anything you specialize in. So unlike the others, you can pick what you want me to train you in." Yume takes a deep breath. "G-genjutsu. Please teach me genjutsu."

Anko smiles and nods. "Now that thats out of the way, time for lunch. I know this restaurant with a super wide selection." She takes you all there and orders all your favorite foods for you. The waiter rearages your your banana and nuts to look like a dick and balls. All the girls lagh while you hide your face behind the menu.

He then flirst with all of you, but the girls stop laughing and tells him to leave. You get more embarrassed, never getting flirted with before but you tell him your not interested since you think your straight.

The 4 of you chat and have fun, celebrating that your now a team. Once Anko pays for the food and dismisses you all, you finally have some free time. You wanted to try to become friends with Naruto after completing your jutsu and apologize for trapping him in a girly form. Nows your chance.
