Has aura that Kaneki doesn't resist.
Soshiro's forcefields will make it hard for Kaneki to grab them. Soshiro has AD for skill if you really think they're close, he'll just surpass Kaneki, Kakuja is already the start here, he can just cut it up. Kaneki's regen is the main issue but we know Kaneki doesn't have endless stamina, Soshiro could just out stamina him until Kaneki can't regen anymore. He also has more abilities to avoid injury or fatigue also.
Is this Kaneki's enhanced abilities or not?
In any case, the kagune's sharpness and limited contact area will allow Kaneki to successfully break through the barrier, and his kagune can gradually absorb chunks of Soshiro's suit.
Having one extra limb was a significant advantage for Soshiro, so a dozen such limbs in addition to his quinque skills will definitely pose problems, especially considering that his kagune is much more flexible and can freely change shape. Kaneki can also gradually adapt to such an opponent's fighting style; his accelerated perception will be a nice bonus.
Indicate that Kaneki starts in kakuja because his 7-A form is basic. Kaneki's kakuga was destroyed by Furuta, and after that, he managed to deactivate his kagune.
AD+RE will be a bigger problem for Soshiro, and frankly, I'm not sure this match is valid. Hoshina's AD isn't as impressive as Kaneki's. At some point, Kaneki will become too fast, durable, and strong.
Honestly, I'm not sure Soshira will overcome Kaneki's regeneration, given the half-ghoul's stamina and the fact that his final form just woke up from a coma, was drained of all his vitality by the Dragon, and Kaneki was constantly exposed to Kagune poison.
