巨大な扉を開ける。 それだけで、冒険が動き出す。 封印扉の向こうに待つのは、財宝か、敵か、罠か、それとも未知の何か。 1タップで扉を開き、現れた結果を見て「持ち帰る」か「さらに潜る」かを決めよう。 深く潜るほど報酬は大きくなる。 けれど、危険な結果に遭えば財宝を失うこともある。 安全に帰るか、次の扉に賭けるか。決めるのはあなただ。 【ゲームの特徴】 ・巨大な封印扉を1タップで開く、シンプルな操作 ・宝、敵、罠など、扉ごとに変わる予測不能な結果 ・財宝を100%確保する「持ち帰る」と、報酬を狙う「さらに潜る」 ・封印鍵、護符、扉機構の3つに絞った拠点強化 ・扉の自動設置、自動開扉、放置中の大扉発見が段階的に解放 ・最高の一撃は手動開扉に残る、放置と操作のバランス 強制広告はありません。 動画広告を見るかどうかは任意で、視聴しなくても遊べます。 アプリ内課金はありません。 さあ、最初の封印を砕け。

"How many steps did you take today?" Every one of them helps take back a lost kingdom. Demon Prince is a walking x idle RPG where your step count is the fuel for the adventure. Play as a prince driven out of the demon realm, gather the allies you were separated from, and win back your stolen territory one step at a time. No paid gacha. Free to play. - The world moves when you walk Every step you take in the real world earns WP (Walk Points). Pass a step milestone and a new species wakes up, ready to join you. Spend WP on the Prince's Blessings to push an expedition further. Your commute, your evening walk, the trip to the shops - all of it is more of the adventure. - Send them out, then get on with your day Expeditions advance on their own over time. Send your party out and leave it alone. The kingdom comes back to you a little at a time, in the gaps of a busy day. - Build a party that fits together A shield who takes every blow, a mage who clears a crowd at once, a healer who keeps the front line standing - every monster has a role and a character of its own, with its own skills, elements and resistances. Some monsters carry a passive that works just by being in the party - a stat raised for everyone, a resistance shored up, or one fallen ally brought back per battle. Passives from different species stack, so the lineup itself is part of the build. Battles resolve automatically, so what decides them is who you bring and how they fit together. Read who is waiting in each region, and build a party to match. - Every run is a different meeting Even in the same region, the monsters you meet change from run to run. "Who will I run into today?" There is something new every time you go out. - No gacha. The time you walked does not lie. There is no paid gacha. Strength comes from the steps you have taken and the time you spent raising your party, and from nothing else. So: walk. Every step of yours goes into rebuilding the Demon Army.
