ALL WISHES MUST
BE GRANTED
LET IT BE
BY MY HAND!

How the final Battle would work out;

You face Three opponents;

Toyosato no Mimi
HP: 175,000 Weak to: Dark / Strong Against: Light

Soga No Tojiko
HP: 70,000/35,000 ( After Auto Revive via 'Angel's Tear' ) Weak to: Earth / Strong Against: Wind

Mononobe No Futo
HP: 70,000 Weak to: Water / Strong Against: Fire

Strategy:
The Battle starts out with Miko with Futo supporting. Ignore Miko for now and immediately start working on taking down Futo. Reimu/Sanae's Blessed Drops Linked Arte works well here since it is Water Elemental, usually dealing above 12,000 Damage. Try keeping Futo knocked airborne to avoid having those annoying knock down artes of Futo's from going off. Once Futo is down, Miko will be alone.

Take this quick chance to heal up and begin your assault, switching to Reimu/Marisa or Youmu Link mode. Once Miko hit 100,000 HP, Soga appears and automatically links up with Miko. Things will get hard from here. Concentrate on taking out Tojiko to prevent Sun Flare or Thunder Blade from going off. Her attacks can inflict Stun and Sealed Artes, so heal accordingly. Once you take down Tojiko, she'll auto revive via Angel's Tear. When she does this, she automatically goes into Overlimit state. START GOING APESHIT ON HER! Do whatever it takes to prevent her arcane artes from going off or the party eats an Indignation, dealing at least 4,000 damage per person.

When Tojiko is down for good, its finally time to take out the head honcho. Miko will use attacks that have her move around alot so it may be difficult to lock her down via combos, especailly with her Iron stance in place. Keep Sanae away from Miko and switch her AI focus to Healing. Miko's Mystic arte, which goes off automatically at around 40,000 HP remaining will most likely take out Reimu/Youmu. When this happens, pop any Omega Elixir's you may have and finish the battle off.

Congrats; You finally cleared the Main story content for Tales of Gensokyo XIII.
