Katarina

Katarina (カタリナ Katarina) is one of the exclusive characters in Shin Monshō no Nazo. She joins the 7th Platoon of the Altean Knights along with My Unit, Rody, Ruke, and Raian and aspires to be a tactician.

Unknown to her friends and allies, she is in fact Eine (アイネ Aine), one of Eremiya's assassins. She was ordered to kill Marth, but her attempt was easily thwarted. Although she is revealed as a traitor and defeated by My Unit at the end of the Prologue, she can still be recruited if My Unit talks to her three times in Chapter 16x.

Overall
As a boss, Katarina will not have much of a problem making short work of any unit with low resistance with Elfire, so precaution must be taken when fighting her. However, when joining as a Sage, she has low base stats, notably very low Luck and Resistance. However, should you choose to fight with her, you can take advantage of her growth rates for HP, Skill, Speed and Luck, all of which are impressive for a pre-promoted unit.
