UPD: All the characters were solved, thank you all.

It turned out that each letter has its own message, which is addressed to the deceased relative or friend of each hero. Reading and crying

01: “Missing you mom. Maybe I can cool off this… sister.”
02: “Rest in peace, daddy. And yes, I haven’t burned it yet. You were wrong again.”
03: “I told you I would never die. No matter how much mob you have to donate.”
04: “I’m sorry I killed you. The reef is no different.”
05: “Well, buddy… But I still became the most accurate.”
06: “See you Spoonchik. It’s not a pity to die blowing up what you love.”
07: “Yes, I’m the last of our kind… But there was no one better than you.”
08: “There will always be a chair for you in Shattered Moon.”
09: “I’ll free the sisters. Watch over us from beyond.”
10: “My flight will not stop until death robs me of my wings.”
11: “Even Duran would outsmart you, but I miss your laughter so much…”
12: “We’re keeping the whole world at bay, Yaovi. If only you were there…”
13: “This is not the kind of silence I wanted. Come back to me, please.”
14: “Poor… sapling… You… could… grow… a mighty… oak…”
15: “I killed so… many… trees. And they keep growing and growing!”
16: “I just want to be with you. No one answers my prayers.”
17: “What can I say… It’s good that you don’t see what I’ve become.”
18: “I miss you, old man. Your trusty cleaver is still with me.”
19: “By the horn, you’ll be proud of me.”
20: “I would like to know your love. And not to know the life of the Sister…”
21: “I told you not to run to the wall of shields, fool. See you in hell.”
22: “Death found you only in some of the dimensions… So perish in the rest.”
23: “They don’t understand my case. They don’t understand that the plague is necessary.”
24: “The world needs you, Etienne. Needed more than ever.”
25: “We miss you a lot, hare. Sorry for those hugs.”

Looking forward to an event in the afterlife with the participation of these characters? The list of characters is in the post above.
