This is a question that many people will ask and think they know the answer to.
Obviously I feel sorry for the poor guy... Not useful, no girlfriend, not powerful, no girlfriend, not the best looking person, no girlfriend, and so on...

Wrong!

Adan is obviously the best and most useful character there is.
It is just that no one realizes it yet! Adan is often put down by how slow he is and how he resembles Frankenstein (some people may suggest a speed ring to solve the speed problem, but it won't help that much). Not at all!

Adan has high HP and Defense! Most people give him that much credit, but do not go any further than that. Adan can take a beating, and if you give him a good sword, he can wipe out groups of non-mages all by his lonesome!

Adan and Fury
Fury: Adan, are you alright?
Adan: I'm beat. Damn the desert!
Fury: Hee hee, it'd be easier if you could ride on this pegasus.
Adan: Yeah, if I lose 100kg first.
Fury: Adan... don't die.
Adan: Absolutely. I've got such beautiful bride as Fury, how can I die?
When we're done with the war, we'll go to Silesia. We'll run a little shop together.
Fury: Oh, how I wish for that...

Adan and Ayra
Ayra: Adan, are you okay?
Adan: *Pant* *pant*... so tired. I hate this heavy armor.
Ayra: *Giggle* But I like your being masculine.
Adan: Ah, I'm so happy to hear that.
Me too, Ayra, I like your being feminine.
Ayra: I'm feminine...? don't be silly.
Adan: No, I know.
There's nobody as cute as Ayra.
Ayra: Adan, you got a fever or something?
Adan: Oh, let me finish my talking. Ayra... I love you.
Ayra: Wha, what the... you silly thing...

If Adan has lover
Adan: ...Even I end up getting married and have children. I gotta work hard for my family now, and be more careful not to die so soon... Hm? what's this, looks like an antique book. What does it say... this is greek... Hm,... Mmmm!!! What, what the, this feeling! My senses got so much clearer...

Adan: Sigh, how sad... I am such a strong and well-built man, but everyone makes fun of me... If at least I could re-attack like Alec, maybe I'll become more useful too... And then maybe I, too, can get a girlfriend... *Sigh*... life is tough for a man... Erm? What's this old bracelet laying around here? Looks like a bracelet of some magic, but let's try it on... Hm...mmm...!!! What, what a feeling! Ohhh..., now I also have the power of Advancing...
