Hasenkura, the turn player CAN cast Dragoenergy in response to the non-turn player's Dragoenergy. As Kota1908 said, Counter play timings work like this:

1. Play timing begins.

2. Player A (turn player) may use one card or ability. (During the battle phase, the card or ability must have 'Counter' to be used.) If so, move to step 3. If not, move to step 7.

3. Player B (non-turn player) may use one card or ability with Counter. If so, move to step 4. If not, move to step 5.

4. Resolve the card or ability used by Player B in step 3.

5. Resolve the card or ability used by Player A in step 2.

6. Return to step 2.

Once Player A has passed priority in step 2, by choosing not to play a card or ability, play moves on to step 7. Player B can now start his own chain.

7. Player B may use one card or ability with Counter. If so, move to step 8. If not, move to step 12. (In your example, this is where the non-turn player is using Dragoenergy.)

8. Player A may use one card or ability with Counter. If so, move to step 9. If not, move to step 10. (This is where you said that the turn player wouldn't have a chance to respond, but he actually gets to use one Counter here, for example, his own Dragoenergy spell.)

9. Resolve the card or ability used by Player A in step 8.

10. Resolve the card or ability used by Player B in step 7.

11. Return to step 2. (Player A once again has priority to play a card or ability again)

Once Player A has passed priority in step 2, and Player B has also passed priority in step 7, move to step 12.

12. Play Timing ends.
