Diamond Realm

The Diamond Realm is a location in the SMT series.

Description
A place that exists outside the normal world, time in it moves faster than in the real world.

TFR/Season 6
Suou Tatsuya, Yuki Makoto, Komaeda Nagito and Kadoya Tsukasa arrive after Kadoya desperately casts Toraport in an attempt to save them.

They are greeted by Hagakure Yasuhiro who has been residing here ever since somehow smoking his way up here. He gives the party the offer to get blessings if they can defeat phantoms from the realm. Makoto is matched against Doomguy and Komaeda against Mastema.

Before Tatsuya has to fight Kadoya for a blessing, he reveals that he is actually himself from another timeline that was doomed, and desperately took a last resort opportunity by a complex man to try again.

After they recover their strength, Hagakure bids farewell, and they return to the new world that awaits them...

TFR/Season 7
After wandering through fragments, Leon S. Kennedy and Saihara Shuichi arrive at the Diamond Realm through The Vents, meeting Hagakure and being forced to waste time for a blessing as well, they face "The Mystery Masters" Adachi Tohru and Manny Pardo.

TFR/Off-Season 8
Leon and Saihara notice Hagakure has disappeared and they still don't see any exits. Waiting for what seems like an eternity, they theorize that he must've left through the hard-to-reach vents around the place. While thinking about how to reach them, a strange sensation spreads through Leon's body and tells him something isn't right, but is unable to alert Leon enough right before a Shot-Put Ball falls on his head.

Waking up in a strange world, eventually he would learn he found himself in a Sinless World, and his only choices were remaining forever or bringing sin into such a world by the way of bringing death and despair to Chris Redfield. At the end of the day, Leon wakes up in the Diamond Realm once again, wondering if it was all just a dream. But if it wasn't, then it meant... Before he could think further, a voice approached. Captain Price had arrived.
