Koike chuckled as Miharu explained his plan. It was quite clever thinking of him, but Sakura had thrown the kunai after they both had recieved a hug. Koike wondered why Miharu had taken the cloth, but on the other hand, his brother had the best plan at the moment. Still Koike didn't feel comfortable as the test looked too easy.
Following his brother, Koike held a close eye out for the surroundings as he expected an trap or ambush from their new sensei.
He thought and then spoke to his brother of his thoughts. ''Bro, stay wary... I have a bad feeling about this... I mean, doesn't this looks too easy to you?'' Koike already was readying himself to block any attack with his arm guards. After all, they reminded Koike of his promise to himself : to protect his brother from any possible harm.
''Also, that was some clever thinking with the cloth. I bet she doesn't know you damaged her cloack...Else we are in some great trouble, aren't we?'' He spoke to Miharu with a cheerful tone and chuckling a bit before keeping a close eye on the surounding as he followed his brother.
