Sooo

27-28 at best since he just gone to the dungeon right after he manifest his abilities, when he awaken, he's just on his way from high school with his friend (that one friend he held dearly, even to the point it makes him a trauma of justice)

Oh.. So he is okder than ML right.. Btw, does any of his old guild member survived? I think I saw a blonde woman on whelchair..

29

he doesn't have a guild, merely got recommended by the association with his other friend, in another words, he's freelancer, sadly, only 4 that came out, the rest is dead, by suicide, only his one friend that still alive, even that woman suffer too that she cut her leg, not many people knew his abilities aside of shielding, andwhen you say that mc is older than ml it's true, ml is 22, 4 years since he first awaken in 18 y.o, and the great dungeon happened 12 years prior, tho what they experienced it around 300 years in total, make sense for someone to not wanting to live, that list is his rope of line to keep him from dying, also invented by his friends in the dungeon since they thought it's too cruel to make a teenage to shoulder 1,2k fates and carrying it till the end

note: the commenter above is right, I did miscalculated, I thought the cataclysm back then is 10 year, it turns out to be 12, then yeah, he's 29 y.o as of now, sorry for that
Σ(っ°Д °;)っ

thank you for your answer, I was searching up again only to find I lost in calculating, I thought the great dungeon/ cataclysm happened 10 years ago, turns out it's 12 (≧∀≦)

ah when I said suicide, is out of 4, only two alive now, the other two are suicide right after out from the dungeon, but the rest..... they're fallen soldier #－.－)
