Irwine/Arwin (アーウィン) - Zombie (ゾンビ) - é”物ã®å·£ (can summon nature units) - ナイトシェード
Julianne (ジュリアン) - Crawler (クãƒã‚¦ãƒ©ãƒ¼) [= Sandworms, you can summon them if you have 2 Rooms with the green Floor] - 闘技ã®é–“ (more experience gained for units in the room) - ã‚ャタピラー

I`ve been trying to capture Julianne for ages... no wonder none of the starting Monsters worked.
Campaign Menu
1. 侵略 
Invade. you invade human territories, fight em, and take over the town. if you lose the battle here, your pawn won't die, they will just retreat. if you lose the 1st fight, your next fight continues with the enemy HP depleted
2. 敵を挑戦
Challenge enemy. you send a challenge letter, in your next defense sequence, your enemy will be sending stronger troops
3. ãŠå®ã®å™‚ã‚’æµã™
Leak treasure information. many weak adventurers will attack you in your next defense sequence
4. æƒ…å ±åŽé›†
Information gathering. you'll learn each heroine's weakness
Alternative: 調教:xxxx Train:heroine name. Have not tried, but this basically is raping the heroine. I guess u gotta rape several times to get them into your party. of course, you have to capture the girls first.
5. ãŠæ¥½ã—ã¿ï¼šï½˜ï½˜ï½˜ï½˜ï½˜
H scene. with the girls who won't resist, I guess.
6. ダンジョン増築:
Increase your dungeon area. more space=more space to build things up
7. xxxxx強化
Power up a race of your pawn, or your 'max population'. costs bone
8. the 2 options below power up monster are power up for you. your max population and max HP. I believe everyone can read HP so I don't have to point which one is which
9.
Trades. buy bones with money, or buy magic with money
10. 何もã—ãªã„
Do nothing
PS: I haven`t tested all out, so I don`t know if everything works.
