Oh wait, I think I found a ruling for a similar situation.

https://www.zxtcg.com/qa/qa_search.php?n=B04-102-00 Q: You have 8 cards in the hand, and 「B05-036 Blue Guardian, Phecda」 in Square, and then play 「B04-102 Original XIII Type.I A-Z」 from your hand, can you use 「B04-102 Original XIII Type.I A-Z」 ability to deal damage?

A: When 「B04-102 Original XIII Type.I A-Z」 is played and appear, 「B04-102 Original XIII Type.I A-Z」's "When this card appear, if you have 8 or more cards in your hand, deal 1 damage to your opponent." ability and 「B05-036 Blue Guardian, Phecda」's "When this card or your [Battle Dress] appear, you may draw a card." ability activates simultaneously. The resolution of abilities that activate simultaneously is decided by the turn player. Thus resolving it as 「B05-036 Blue Guardian, Phecda」's ability → 「B04-102 Original XIII Type.I A-Z」's ability, and fulfilling the 8 or more cards condition by the time 「B04-102 Original XIII Type.I A-Z」's ability resolves, you can deal 1 damage to your opponent. Based on this, then yes, it seems you can use Animus' ability.
