I matched Rain-san's spell—cast mid-tier attack magic.
Additionally—placed **Raise-Repeat Amplification Chain** along firing line.
Mists skillfully blocked our spells—but numbers insufficient.
Gradually—attack spells began hitting black dragon.
Black dragon tried moving—but Will's precise positioning and attacks pinned it in place.
『Interval! Resume attack in five seconds!』
Rain-san's voice echoed mentally.
Hearing it—I switched to close combat.
Activated **Sharpness Up** on **Schwarz Hase**—closed on rear left leg.
Entered sword range—slashed same spot repeatedly from various angles in an instant.
Previous sword—normal, good and bad.
Could only shatter hard scales—shallow wounds max.
But this sword—made for me, optimized for me.
Material quality—worlds apart.
With support magic boosting **Schwarz Hase** further—severing black dragon's tough leg possible.
Countless black trails sped before my eyes—finally severed rear left leg.
Black dragon's agonized scream.
Remaining three mists lunged at me.
(Note: Will erased second mist earlier.)
Easily dodged—pulled distance.
Right then—Rain-san's interval ended.
Attack spells rained from above black dragon again.
Black dragon—missing rear leg—unbalanced but spawned ten mists.
Previous max: ten.
Faster pace.
Mists intercepted Rain-san's spells—blocked attacks.
I fired **Thunder Arrow** from behind—**Impact** included.
Thunder-attribute spells—superior penetration.
**Thunder Arrow** pierced black dragon body—dealt damage.
(So—this power ignores scales and penetrates.)
Rain-san entered interval again—I moved to close once more.
—but multiple mists attacked faster—abandoned attack, focused evasion while distancing.
In gap—our attacks stopped—one mist wrapped rear left leg—replaced missing limb.
(Can use like that? Interesting.)
Unlike last black dragon fight—still plenty stamina—I admired mist versatility honestly.
Black dragon shifted weight forward.
『Tail attack incoming!』
I instantly read next move—alerted all.
Black dragon tail—unbuffed reaction impossible speed—lashed at Will.
"Won't eat that twice!!"
Will shouted—parried tail with twinblade.
—not just parry—extended chaotic mana blade—stabbed tail.
I timed **Impact** with Will's attack.
Massively boosted blade pierced tail—pinned to ground.
Confirmed tail fixed—I approached base—swung **Schwarz Hase**.
Right before contact—**Impact** on myself too.
One stroke—severed tail.
Black dragon roared—anger and agony mixed.
『Fireball incoming!』
Selma-san's voice in mind.
I moved to see black dragon face.
Flames leaked from mouth.
Black dragon charged fireball.
Simultaneously—cast **Reflective Wall** near face.
Fireball fired from mouth—immediately reversed—exploded inside.
◇
One-sided battle continued.
Will took all hate—parried everything.
When Will damaged—Lucre instantly healed.
Lucre no attack participation—full recovery focus.
Possible because Rain-san hammered high-power spells short intervals.
Selma-san—buff management and black dragon movement monitoring.
Will and I—close to black dragon—limited full view.
Many blind spots—but Selma-san updated constantly—handled attacks fine.
Four simulated black dragon fights mentally all year.
Continued after I joined.
Result: this.
Black dragon helpless before us.
Originally capable of beating it.
Planned every pattern—counters ready.
—No complacency.
◇
Black dragon spawned twenty mists...
"Hah!?"
Will exclaimed in shock.
Natural reaction.
I'd fought black dragon twice—First Unit once—never more than eleven mists.
Guild records—no precedent over eleven.
Twenty—five each toward Will and me.
Remaining ten—countless tiny needles—shot at rear three simultaneously.
(Damn! No holding back!)
That many on rear—even mana barriers—can't withstand.
Dodged incoming mists—built formula.
"**Magic Sword Union – Alteration**!"
Formula complete—activated new storage function.
Spells activate by flowing mana into built formula.
Storage artifact—continuously absorbed/converged surrounding mana—flowed into my formula.
Incomplete original spell activated.
Mana fused with **Schwarz Hase**.
Black sword lost shape—became jet-black fluid/gas/solid-like converged mana—sword-shaped.
"Heaven Flash...!"
**Schwarz Hase** already converged mana.
No time for Heaven Flash mana convergence.
Released Heaven Flash at needles—shockwave erased most.
But not all.
Remainder flew toward rear three.
I took action for next move.
