CardFight!! Vanguard Ruling:
Dragonic Kasier Vermillion
According to the latest pdf rulebook ver 1.07, on guarding, at 8.5.2.2.1:
- When you place guards from your hand, you may only choose 1 unit fom your field for the placed guard to guard for.
That rule means that for Dragonic Kaiser Vermillion's ability which can attack multiple units and at the same time, not allow any intercept, you will need to have separate sets of guard for each units being attacked.

As a further update, Bushiroad confirmed the following information about Dragonic Kaiser Vermillion's effect via a conversation on Twitter:
1. Vermillion attacks 3 unit at one time.
2. Attacked units cannot intercept.
3. Twin Drive only once.
4. Each unit must be guarded separately.
5. Perfect Guard (e.g. Wyvern Guard, Barri) can only be used on one unit.
6. If hit, you may activate Flame of Hope Aermo's (or similar effect units) skill for the number of hits. (Eg. If hit twice, may drop 2 cards and draw 2 card.)
7. Covert Demonic Dragon, Manadala Lord's skill affect all battles Dragonic Kaiser Vermillion is engaged on, meaning Covert Demonic Dragon, Mandala Lord lowers the power of Dragonic KaiserVermillion for all 3 units, not one.
