With Naruto
He saw Rias walk with her peerage and all of them had concerned looks, worried about their out of character King.
"Rias? Why are you here? Aren't you supposed to spend time with your family?" Asked a confused Sona. She and Naruto were discussing a sparring match so that Naruto can point them out their mistakes as part of his training before Rias barged in.
"Naruto, fight my peerage," said Rias in a commanding tone. Naruto raised an eyebrow.
"What happened, Rias? You seem disturbed." Asked Naruto. Though he can see it is futile as her eyes are burning with battle hunger.
"Fight now and talk later," suggested Kurama in a sage tone.
"When did you come back?"
"Doesn't matter now. Now fight," said Kurama, prompting Naruto to fight.
"Yuuto," called Rias and Kiba stepped forward with a sword forming in his hand with its blade made of ice. He launched towards Naruto, with a forward slash.
Reni stepped forward, Naruto gestured her to wait and took the sword head-on and a kunai came to him and he deflected all the slashes and parries of Kiba.
"Akeno," called Rias and Akeno stepped forward, with her hands crackling with lightning.
"Ufufufufu. This is going to be fun," said Akeno, attacking Naruto, while his back is towards her. An ice wall came to life and protected Naruto from the lightning attack.
"Not so fast, Akeno dear," said Reni, stepping forward, her clothes changing into more comfortable robes for her and facing Akeno, who is in her Kuoh Uniform.
"This is going to be fun," said Akeno, as she prepared for the upcoming fight.
Reni's hands were covered with a layer of ice to protect her from the lightning that Akeno sends towards her.
Kiba couldn't move the Kunai an inch and so he change his sword to adapt to the situation.
A demonic sword formed in his hand with a dark blade. It started to glow brightly as the energy from Naruto's Kunai started being sucked into it.
It devoured all the holy energy that Naruto subtly out into his Kunai to test the capabilities of Kiba's sword. His Sacred Gear, Sword Birth adjusted to the situation and made a sword, which he didn't expect.
"That's a nifty ability, Kiba. But you need to push it," said Naruto, a sword forming in his hand. Kiba jumped back as Naruto's range increased due to his sword.
"Do you have a sword? Why didn't you tell me?" Asked Kiba in surprise.
"How do you think I train my Club members in Kenjutsu if I don't know how to use a sword?" Asked Naruto sarcastically. Meanwhile, Kaneko silently made her way towards Naruto.
She is just a few inches from her target when a shadow appeared in front of her and her hand was sucked in. She tried escaping, but couldn't.
At last, with a lot of effort, she managed to get her hand out. Naruto gave her a wide smile as she tried hitting him, but he was gone.
"Nice try, but you should be faster than that to hit me," he mocked. Kiba created another sword to counter Naruto, but it didn't work on Naruto's.
"Can you create a light sword to cancel my shadow sword?" Asked Naruto, holding both Koneko and Kiba in a lock.
"I think you need Holy essence to even try to create it. So, sorry," said Naruto and a blast of shadows shot Kiba backwards and the force is enough to keep him from moving.
"Now let's test your strength," said Naruto, turning towards Koneko. She prepared herself and Naruto's sword vanished and he turned towards her.
She punched immediately as she saw him approach, but Naruto dodged and flicked her on her face, which sent her barrelling.
'Kuroka, what do you want me to do with Koneko?' Naruto telepathically asked the black-haired Nekoshou, who was somewhere.
'What? Shirone is with you? What is she doing there?' Asked Kuroka, replying instantly as her sister was near her lover.
'Rias came here to let off some steam, that's it. Come on, tell me what game shall I play with her?'
'Hide and seek. She likes it a lot.' Replied Kuroka enthusiastically.
'Ok. Let my magic circle come into view. You can see it,' said Naruto and Kuroka did as told. She sat in a comfortable position and watched happily.
"Punch,"
"Koneko Punch,"
"Smash,"
"Hit," were Koneko's attack names as she tried her best to beat Naruto in the impromptu hide and seek the blonde started.
Naruto weaved through her attacks like a master craftsman as he would occasionally touch her on her shoulder to let her know how many times he would have hit her.
"Damn he is fast," Sona heard Rias mutter. She must agree, she didn't see many who can play with Koneko like how Naruto is doing.
