If you play CCG, you can dodge as soon as throwing gadgets so that it drops exact location you were before dodging. This is very effective in any kinds of close fight. Plus the ending result is that you have chance to make an attack and enemy get staggered by your dropped nade after your dodge.

Melee locking provides you to continuously melee your enemy while making your enemy uncountable.

1. Lock target first
2. Melee, then quickly jump
3. Repeat #2 until your enemy dies.

One caution is that if your enemy is pushed back to wall, then melee lock won't work.
For this reason, we highly recommend you use ultimate Asuka. Her melee won't push your enemy back.

Use it to heal yourself by knocking down chasing enemy with ranged attack lol
It worked against Trap in Kaneki sometimes so it will probably work sometimes.

I don't see its particular use in offensive action because its ranged attack damage is so low and also knocking down makes enemy temporarily un-vulnerable.

CCG Tanker build worked better with Ukaku<Leap> than Ukaku because it has to have a way to survive when HP is too low as it is tanking build. Ukaku didn't make me successfully run
