An all too familiar transfer student!

Issei walked with Rias and Asia back towards Kuoh University. "So, we're upping my training then?"

"Of course. We're not just going to teach you to prolong a fight to get more out of your Boosted Gear, we're also going to try to raise your base power as much as possible as quickly as possible. 1 times two is two, times two is four, times two is eight, and so on. Three boosts putting you at eight as an example. But, if you started at 2 instead, you can get the same power with two boosts instead, and get to sixteen with three," Rias explained.

"Right, so while we increase my ability to prolong a fight, we also work on decreasing the need to," Issei nodded in agreement.

"Exactly," Rias nodded, before looking at Asia. "We'll also be training your own defensive and evasion skills. As our healer we'll need you able to hold your own in battle for extended periods of time."

"...Koneko's not going to be throwing cars at me, is she?" Asia squeaked, and Rias laughed.

"No, pretty sure that's just Issei she wants to do that to..." she giggled.

"Lucky me," Issei grumbled sarcastically. They entered the classrooms, and once they were seated, the professor cleared his throat.

"Good morning class. Today, we'll be delaying the lecture for an announcement. We have two students transferring to our courses, starting today."

...two? Issei knew about Asia, but who was the other one? His heart just about stopped when the door opened and... a very, very familiar figure walked in, a smile **** on her face as she stood before the class.

"Hello everyone!" she said with very well acted cheer as Rias, Issei, Asia, Kiba, Akeno and Koneko stiffened. "I'm Yuma! Pleased to meet all of you!"
