Such an opponent is indeed somewhat unfriendly to Reiger, there's a poor compatibility.
To deal with such an Allen, unless Reiger unleashes his limits and gives it his all, he can only pull out all the stops, unable to be restricted to just one or two combat methods like before, using only one breathing technique.
Thus, shortly after the battle began, Reiger indeed successively used the Breath of Wind, Breath of Thunder, and Breath of Moon.
Breath of Wind focuses on attack.
Breath of Moon focuses on defense, and uses broad-area attacks to force the opponent back.
Breath of Thunder is used for bursts, allowing Reiger to keep up with Allen's speed.
In this way, Reiger can face off against Allen, whose speed surpasses that of a typical Lv.8, while in a Lv.6 state, without being at a disadvantage.
Of course, Allen surely finds this result somewhat unacceptable.
