[AtomicBeast1954]

So far in Blade, they not only got Kenzaki but also Hajime.

In Agito, they got Shoichi.

My hopes for the later tributes would be:

Den-O: If they can't get Ryotaro, I hope it's either Yuto or Kotaro.

Kiva: I hope Wataru comes back along with Nago, Taiga and Otoya.

Drive: More than just the Drive cast, bring in Double cast since they did a special crossover with it.

Hibiki: Unsure.

Kabuto: They can still bring Tendou and Kagami.
