Prepare for the game

"That's awesome Issei-kun ! I never think you can be such agile"

"The same for you. I used to think swordsmanship is just to perform"

Issei and Kiba praise each others's fighting ability. Kiba has showed his swordsmanship in the fight with fallen angels and Issei is starting returning to his former days as a real fighter.

"Actually, i think you should choose Koneko-chan to practice. You both use punch so it will be suitable than with me"

"I had asked her but she doesn't want. Our little Koneko-chan truly hates pervert"

But Kiba gets the right point. Riser has himself, a hand fighter like him and his queen, a magician. Even if he can deal with the others, the two of them will be a big trouble. And Riser's last name, Phenex, with means he or maybe all of his team will have someone or something to recover their power immediately.

"We need more prepare ... something can anti their healing and a powerful attack to get rid most of them"

Using the stones power is not a wise choice at he still not masters theim. If thing goes bad, Raynare will be free.

"Having a powerful weapon but can't use ... it ..."

Wait, the stone is not his original Sacred Gear, which mean ...

"I remember i have something to do. See you later Kiba"

Without receiving a goodbye from Kiba, Issei goes quickly to his hideout to experiment his newfounding.

"Increase my power"

"Boost"

As he thought, Boosted Gear's original ability is still there, but being relacing the main function by the stones.

However, like with the stones, Issei doesn't master all the power of the high-class Sacred Gear.

"This is enough. Now i can make a good preparation"

Satisfied with the answer, Issei activates Mind Stone to check Raynare and see her being beaten by some women for "stealing" their husbands/lovers. More satisfied for him tonight.
