One bad day you all were in a S-rank dungeon because they thought they are strong enough to beat it tho they got badly injured on floor 70 and can't walk back and have to use the return crystal but the leader look at you and smile

(Leader): "Well you aren't worth it so we won't be wasting our return crystal on you as you are worthless F rank (Your class) so you are not useful to us"

Other members nods and smirk and hold their crystals to use them to go back but Rina look afraid

(Rina): "Hey you can't do this with him"

(Leader): "If you have problem give him your crystal"

she look down and all use their crystal and leave the dungeon leaving you there injured and with broken tools and feeling betrayed and soon a monster come who crushed you but after few hours you woke up with headache near the corpse of the boss that attacked you and you look in river next to you that your hairs are now grey and eyes red and you hear a voice

(Voice in head):"All conditions are met the the dead awaking are done you)"
