When I was still a kid that is, before I became a magic knight, I remember saying that I didn't want to reveal my power but my obsession with op mc wouldn't let me so I thought of a plan. Instead of revealing I am op directly, I will just act like I am weak, watch from the sidelines and when the time comes reveal my power.
Mimosa gets hit by some spikes made of diamond. Klaus opens his grimoire and says "Steel magic, steel lance ". A bunch of lances made of steel form out of thin air and attack the enemy. It fails miserably and Klaus flies back also injured after being hit by another diamond spikes.
Yuno uses his wind magic and creates swords made of wind and attacks the enemy. The enemy says "Diamond magic diamond armour " and makes all of Yuno's swords useless. Yuno gets low on magic so he attacks the enemy with weak crescent-looking wind slashes. The enemy says "Let me show you the difference between our power" and creates a giant sword and attacks yuno who was low on mana.
I who was healing and tending to Mimosa's wounds using her own magic saw this. I heard Mimosa say " I can take it from here go " and she opens her grimoire and continues where I left off. I said "Moon magic, crescent scythe " and cut that giant sword in half.
At the same time, Asta had also arrived but I cut the sword just before he came. Then Asta and I team up to defeat the enemy while Noelle guards Mimosa with some kind of water ball-looking barrier. Asta runs off on his own and reveals that his magic is anti-magic. Klaus hears this and calls him lucky but sees his muscles and after realizing how much he must have trained he shuts up.
I whisper to Asta a plan to defeat this enemy. Asta nods his head and continues with his attacks. I also helped Asta by using long-range magic spells. The enemy was being cautious of Asta for his anti-magic and cautious of my moon magic. The long-range spells I used were only moon magic spells. I didn't want to reveal that I have copy magic to my enemy just yet.
The enemy used the giant sword attack again. Asta slashed it and destroyed it. We were waiting for this attack after all, this attack blocks the enemy's vision all to prepare for a single element of surprise. I said "Sun magic scorching sun" and used the attack Eliana used but with some improvement. The enemy sensed a huge amount of mana in that attack and used many diamond spikes to block that attack. All the diamond melts from the heat of the ☀️ and it reaches the enemy. The ☀️ penetrates his armour and explodes sending him flying.
I made it explode after it penetrated his armour or else it would have put a hole in his stomach. I have to make sure I don't make Eliana mad or else I might die. We won, I have a high five to Asta and it looked like Mimosa was fully healed.
After some chatting and Asta and Klaus fighting each other with words we agreed to let the Black Bulls go inside the Vault first. But we had no way of opening the door. Luck touched the door and said to Asta "Looks like the door is made of magic too so just slash it with your sword ". Klaus said " There is no way you can open the door that easily " and Asta cuts open the door as Klaus was speaking. What was on the other side shocked us to the very core
