FE3H - Protagonist
(default: M ベレト Byleth, F ベレス Bylese?)
You originally work as mercenary but your talents get noticed so you become a teacher in academy. Your mom already passed away so you live with your dad who was leader of Knights of Seiros & now leads mercenary band.

FE3H - Geralt (ジェラルト)
A legendary being who is also said to be the strongest knight in history. Was summoned to Garreg Mach Monastery together with the protagonist, which makes him return to the Knights once again.

FE3H - Sothis
A mysterious girl who looks young but speaks in an old manner. She saves the protag at the fateful night. She normally doesn't show herself up and she speaks with telepathy into your head, so no one except you notice her. She also lost the memory of her true self.

FE3H - Edelgard
Princess of the Adrestian Empire who has been promised the position of the next empress. A talented woman who has a cold & noble atmosphere.

Adrestian Empire has the longest history. Many people here are more skilled in magic than weapons.

FE3H - Dimitri
An eloquent youth who has good manners & embodied chivalry, but he somehow holds a shadow.

Perhaps because the Holy Kingdom of Faerghus is known for its knights, many of the students here are good at using spears.

FE3H - Claude
A friendly youth whose smile fits him well. Although he doesn't seem like thinking of things too deeply, he has a sharp insight.

Compared to the other classes, Golden Deer has more commoner students. Many of them are also good at using bows.

FE3H confirmed having a time rewind system, made possible by Sothis' ability to turn back time. The system is similar to FE Echoes where you can rewind per movement but the amount of usage allowed is also limited.

FE3H
Terrain effects: Other than determining movement costs and evasion rates, some spots may have gimmicks such as healing HP or even warp a character to another spot.

When the game is just booted, there will be choices for Normal/Hard difficulty and Casual/Classic mode.

FE3H Class Change now uses a Qualification Exam system: Character needs to spend Exam Passes and the chance of passing improves with correct skill ranks. Once the class has been unlocked, the character can freely change back anytime. Level won't go back to Lv1 either.

Ranked skills in FE3H:
剣術 Sword Skill
槍術 Spear Skill
斧術 Axe Skill
弓術 Bow Skill
理学 Physics (Black & Dark magic)
信仰 Faith (White magic)
飛行 Flying (Flier classes)
重装 Heavy Armor (Armored classes)
馬術 Horseriding (Cavalry classes)

Each char has good & bad ranks

Characters in FE3H start in Commoner or Noble class depending on their origins, but these starting classes are same stat-wise: Can just use some magic with no other highlights.

The first class upgrades after Lv5:
Myrmidon (Sword)
Soldier (Spear)
Warrior (Axe & Bow)
Monk (Magic)
