★ INTRODUCTION ★
Today we will be looking at the mechanics of the newly added S-rank Battlesuit [Miracle ☆ Magic Girl].
She is a new Fire/Ignite MECH-type, S-Rank battlesuit.
She is a Chakram user and her role will be that of the main DPS.
Her unique feature is to be able to increase the Ignite stacks on enemies, similar to Griseo and Susannah have for Bleed.
She is also able to increase the DMG output of the Ignite effect and thus can even deal a lot of DMG after switching out.
After certain actions Sirin is able to use a special Weapon Skill.

Summary
What are the most important things to know?
Sirin deals most of her DMG through Ignite and her specialty is to increase the Ignite stacks on the enemies.
This means her goal is to accumulate as many Ignite stacks as possible.
Her Special bar should always be maxed out to be able to unleash the SEQ 2 of her Charged ATK because this increases the Ignite stacks even further, restores more SP and deals significantly more DMG.
Note!
Hold the [ATK] button until she unleashes her Charged ATK on her own.
Releasing it too early will cast der SEQ 1 instead of the SEQ 2.
It is also important to pay attention to her Weapon Skill, when it starts flashing it means that her Joint ATK can be used, which deals high DMG and enables buffs.
Overall I'd say she isn't complicated to understand.
★ RANK UP ★
[Miracle ☆ Magic Girl] is available in the Expansion Supply and in the War Treasury Shop and thus can be ranked up pretty easily over time.
• 280 Crystals = 1 pull
• 100 pulls = guaranteed UP Valkyrie
• Worst case 28000 Crystals
OR
• 480 Ancient Willpower + 480 Ancient Legacy (until 7.2)
after that:
• 640 Ancient Willpower + 640 Ancient Legacy
• 8 Ancient Willpower + 8 Ancient Legacy = 1 Fragment
(max 4 per week, 2 extra Frags once Valk reaches SS)
Tests
Extra Note!
S2 is a great upgrade for Memorial Arena fights because of the Initial SP.
★ PLAYSTYLE & LINEUP ★
[Miracle ☆ Magic Girl] is a straightforward and easy to play (& understand) Valkyrie.
Her Ultimate is ideally used at the end of her Rotation because it gets stronger the more Ignite stacks the enemy has and these are accumulated during the Basic ATK's, Charged ATK and Joint ATK's.
Also her QTE should be turned on because it applies Ignite and recovers quite a huge amount of SP.
Rotation example:
Sirin enters the battle with QTE after both supports applied all of their buffs.
Use Basic ATK until the Weapon button flashes and use Joint ATK.
If all Basic ATK's hitted the enemy, the Charged ATK can be used to unleash the SEQ 2 (expend the full bar)
After that the Weapon button flashes again and should be pressed.
The enemy should ideally have the maximum amount of Ignite stacks (if possessing her signature Weapon) and then the Ultimate is casted and Sirin will leave the field.
Note!
This is just one example to get an idea how she can be played.
Rotations always vary with the situation and Boss.
Please refer to the Rotation and/or Gameplay section of this Guide for a visual look at it..
Posting them here as a GIF would be too big unfortunately.
Boss Coverage
[Miracle ☆ Magic Girl] will be a strong Fire/Ignite DPS and will top-score the newly added Bosses and some older ones like Andrius and Benares, especially during Ignite Weather.
Her coverage will be decently good.
She will also be a nice Alternative against MECH-type Fire Bosses as well.

★ TEST RUNS ★
Note!
All following tests were done using the signature equipment for every other team member.
Analysis
The Tests show that her Weapon and Stigmata set are both very important for her DMG output.
Since the Sigmata set is available in the Foundry that means only her Weapon should be aquired from the Gacha.
It is not just important for the DMG itself but also for SP and some Boss mechanics.
Rotations
★ GAMEPLAY ★
★ CONCLUSION ★
Is it worth to invest in her?
If you are lacking a Fire DPS, then yes for sure!
[Miracle ☆ Magic Girl] is strong and easy to gear, which is another reason to try and build her.
Although I wouldn't say she is mandatory to get, it sure makes the newly added Bosses easier.
As well as some older Ignite Bosses and Andrius.
However the fact that she only really needs her Weapon from the Gacha should be considered as well.
I'd say if you have the ressources to get her Weapon and don't have any other more important Valk to buy in the War Treasury, it is definitely worth to invest into her!
That's it~ 
Thanks to every captain who will read my guide and I hope it will be useful to you! 
As always I wish everyone lots of fun in Honkai and may Ai-Chan bless you with luck in the gacha!
