Chernobog, former Dark Lord of Bald Mountain taken from his frozen peak by the hero of his land, is enjoying experiences in his new life at Shinjuku Academy that he could not partake in back home. His latest novel challenge is Sports Day, in all of its whistle-blowing, confetti-flying glory. He does his best at games with rules he has never heard of, belly bouncing in exertion, as his heart warms to the reality that he is out on the field, sweating with his friends under a shared sun. When the suggestion of baseball comes up, he volunteers for the position that lets him work closely with his hero, wearing not his crystal armor but the chest protector, mitt, and mask of a catcher. Who could have imagined that the hero and the dark lord would join hands to form a battery on the sandlot? Or that the powers of frost he dreaded so much would feel so nice after the game? A smile came over Chernobog’s face when he realized the day he never thought would come had arrived, and that he would appreciate this gift of his. The sun shines down from above, the long winter is over, and another page of his youth has begun. In the one standing before him, he sees the visage of the hero of Kitezh who brings forth spring… and someone he would very much like to play ball with.

かつて極寒の地から「彼にとっての勇者」の手で連れ出された禿山の魔王。故郷ではできなかった様々な体験を、この東京の学園生活で謳歌している。今回挑むのは、ホイッスルが鳴り響き、紙吹雪の舞う春の運動祭。見慣れぬ競技やルールに、その大きな体躯を揺らしながら一生懸命頑張る。仲間と共に汗をかくという事実に、魔王の心は温まるのだ。そしてチェルノボーグは我が勇者の伴侶たるポジションに名乗りを上げた。氷晶の鎧ではなく、キャッチャープロテクターをまとい野球のグランドへ。勇者と魔王のバッテリーなんて、聞いたら自分を生んだ親も驚くだろう。ずっと忌み嫌っていた氷雪の力も、投球後のアイシングに使ったり。まさか、この授かりものに感謝する日が訪れようとは、と笑う。長い冬が過ぎ、これより始まるは甘酸っぱい青春の１ページ。彼は目の前の相手に「春をもたらすキーテジの英雄」の姿を見る。いざ、高らかにプレイボールの宣言を。

曾經由「屬於他的勇者」親手帶離極寒之地的禿山的魔王，如今正在東京的校園生活中，盡情享受著過去在故鄉無法體驗的種種經歷。這次迎接他的是哨聲響徹、彩紙紛飛的春季運動祭。面對從未見過的競賽與規則，他拖著龐大的身軀努力奮鬥著。光是能與夥伴們一同揮灑汗水，就足以讓魔王的心感到溫暖。而切爾諾伯格也正式宣告，自己要爭取成為勇者伴侶的位置。這次不再披上冰晶鎧甲，而是穿戴捕手護具，踏上棒球場。勇者與魔王組成投捕搭檔――這種事恐怕連自己的創造者都料想不到吧。就連過去一直深惡痛絕的冰雪之力，如今也會被拿來當作投球後的冰敷手段。「沒想到竟然會有感謝這份天賦的一天。」他笑著如此說道。漫長的冬天已然過去，接下來將是酸甜青春的全新篇章。眼前之人的身影，令他想起了那位「為奇鐵茲帶來春天的英雄」。那麼，就高聲宣告――比賽開始吧。

秃山魔王曾经被“对他而言的勇者”之手，从极寒之地带了出来。如今正在东京的校园生活中，尽情享受着过去在故乡无法体验的各种经历。而他这次所挑战的，是哨音响彻、纸屑飞舞的春季运动祭。面对从未见过的竞技项目与规则，他摇晃着那巨大的躯体，拼尽全力地努力着。与同伴们一同挥洒汗水这一事实，让魔王的心中充满了温暖。于是，切尔诺伯格站了出来，宣称自己要成为那位勇者的伴侣。他褪去了冰晶的铠甲，转而装备上捕手护具踏上了棒球场。勇者与魔王的投捕搭档，要是自己的创造者听到，大概会大吃一惊吧。曾经一直深恶痛绝的冰雪之力，如今也能在投球后用于冷敷。他笑着感叹，真没想到，居然会有感谢这份力量的一天。漫长的寒冬已过去，自此开始的将是酸甜青春的全新篇章。他在眼前的人身上，看到了“带来春天的奇铁兹英雄”的身影。现在，高调地宣布比赛开始吧。
