"Don't sink my boat!" D: "I'll sink your boat." :D
This is late, but I want to see a 4-koma that goes like this: 1: Mononobe no Futo standing on her boat throwing lightning around (alternatively, referencing her Spell Card where she actually rides the boat). 2: Onozuka Komachi standing on her boat, holding her scythe and throwing coin danmaku. 3: Murasa Minamitsu calling a rainstorm and/or tidal wave on Futo's and Komachi's boats while they appear worried or scared of their boats sinking. 4: Futo and Komachi sitting on either side of a table, with a Battleship board game between them; Minamitsu pours water over the game boats with her ladle, Futo pulls back her sleeve in an "I'm about to punch you" pose, and Komachi sharpens her scythe while glaring at Minamitsu. If such an image ever gets posted on Danbooru, it should be (made to be) worthy of at least pool #1246 (Digging Your Own Grave), pool #2005 (Mundane Made Awesome), and pool #1384 (To the Death).
